Thank you for chiming in, Clint. The info is very useful. By the way, that was me that made the 5-10 minute comment on the belt, and I stand by it. Granted, that was with 2 people, one to push the tensioner and one to slip the belt off and on. Alone, I can see that job taking a whole lot longer. I don't know if the techs there help each other out or not, as sometimes it's too busy, or it's just simpler to have one man to a job unless it absolutely requires 2.

I'm no mechanic by any means, but I've done a belt on a Cobalt, as well as some other cars. I try to do what maintenance I can to save myself some $$$ down the road, you know? It's not like my old Pontiac where it circles the motor mount or anything. *That* particular job was a true PITA.

Regardless, thanks to you and Oni for helping clarify and fix the issue Back2GM had, and as well for your future input.

Edit: As a note as well, I also bought my car at Bill Heard, along with Oni, and I take it there when stuff needs to be done. Good to know you're back there.

 

i think what he is referring to is the belt assembly ie pulley setup. He mentioned that after a new pulley setup is installed it becomes incredibly easier to swap pulley rings of the same size though in reference to that information if your installing a stage 2 from a stock car I am sure it can take quite a bit of effort to complete

 

That's true. I helped one of the redline guys install the stage 2 hub with just the pulley puller, and that was truely a handful. But the modular system is great! The rings change out so easily once you get that thing mounted. That took the brunt of the time - getting the stock ring off and getting the new one on.

 

damn I got the pulley swap down to a science... I think it took me a little over 30min to do the pulley swap, remove and reinstall s/c and stgII belt

 

Screwdriver, push down tensioner, slip belt off, re-route, slip back on? I could do it in 2

 

If the pulley puller goes like planned. Some are tight as hell. Also I could see problems removing the injectors if you dont follow the steps

 

true... I haven't had injectors take me over 20-25 min yet (did about 7-8 swaps already) pretty straightfoward

 

That's was my problem... guy had never worked on a SS/SC (Didn't know at the time), in fact no one had (I'm one of the only ones in town) and didn't follow the instructions... or even look at them for that matter... until he tried for 30 min to an hour to pull the stock pulley off by hand. As you can read in my previous statement in this thread. There were a lot of times I noticed were "wrong". When they told me the price it seemed right... 4 hours of work - $407 ($384+tax... ONLY because I was use to the Pontiac place across town (Labor is like $95/hr). BUT, when I discovered that the Reflash was not done... It rang a bell... so I had them give me the detailed list of times (Refer to previous post).

Since then, it's gone to hell for me. Stage2 has become more of a hassle then something fun that I can enjoy. I ALWAYS go to this dealership. My problem I guess is that I know what it is like to be on that side... I work for an ATV, Crotchrocket, Dirt bike place... so I have a hard time yelling and saying "You don't know what you are doing... I'm being overcharged... ARRRRGG!"

But I am going to give myself a little time to cool down... and then I am going to approach them with the issue. And GMWORLDCLASS, I'd appreciate some input from you... Look at my install times. Everyone is saying injectors should only take half an hour... hour tops... then why did mine take 1.7? Is that someone doing it for the first time... or is that someone not knowing what they are doing?

Sorry for the rant.... But I need help

The higher number refers to "customer pay" labor. Not accounting for overlaps it's easy to see how they add up to 5.6 hours when you add spark plugs to the mix. So like I stated earlier, 4.0 hours labor is quite reasonable without spark plugs, 4.6 with plugs. If you pay less, good for you. If you pay more than 5.0 without plugs or 5.6 with plugs, try to negotiate.

Just asking for a quick update as to the rev limiter. People who have gone back to the dealer to get it reflashed, is it in fact a 7000 rpm limiter???

I am going to the dealer after class to get my stage 2 reflashed.

Back2GM, is your stage 2 rev limiter 7000 after you got the reflash??

Thanks

 

my stage 2 had a 7k rev limit immediatly after i drove it off the lot after the install

 

If you read earlier in the thread, some of us got a BAD stage 2 tune over the weekend. I was wondering if any of those people have gone to get the problem fixed and if it corrected the rev limiter to 7000

 

Yes... my Rev Limiter is now 7000. They actually NEVER reflashed mine... didn't know he had to. Till I brought up the fact that my Rev limiter was still at 6500.

 

Gotta love those incompitant dealers!

 

Yes, BACK2GM got an improper tune, but now has the proper flash and has the 7,000 rev limiter.

 

So, mine was reflashed and the dealer had me contact Chevy customer care. They are investigating and said they'll contact me next Tuesday. My case is a bit strange. Some times it seems to 'hesitate around 6500 and then continue to 7k, others it goes straight to 7k no prob (I'd say about 80% of the time it goes to 7k as normal). I think there was one other person in this thread saying this happens to them. I'll post back with what they say.

 

I would just like to finish out my problem w/ the Stage 2.

Went and got it reflashed and now the rev limiter is cutting at 7000 like its supposed to!!! Only took the dealer about 2 hrs (they were busy) and the problem was fixed. So I have a complete Stage 2 now!!!

Car feels smoother through RPM range and seems to pull alittle harder, but not much.

So thanks Oni for your info and I hope the rest of you get your rev limiter problems fixed.

 

you might be experiencing the issue with the tach being ~500rpm off due to the slow instrumentation panel communication link. There might be a fix for that and you shouldn't have to pay for it since the issue also occurs with stock cars though stage 2 appears to amplify the issue

 

 

well I had the reflash done on09/05/2006 and I installed the injectors and the a 3.0 pulley from zz perfromance.You guys got me worried. I've shifted and definatly feel a difference but have not taken it to the full7000 yet . I will check mine as well . I know this for sure though I'm boosting toaround14-14.5psi. I'll keep you guys informed.

 

Well took it for a drive up to 7000rpm. No problem here.

 

Well the only thing to dis-prove that would be that most of the time the car revs straight to 7k. Only a few times so far when the rpm's sort of hiccup around 6.5k so that makes me think this wouldn't be the case. Who knows...the guys is supposed to call me back tomorrow.

 

So I contacted GM about this and they are investigating. They were supposed to call me back this past Tuesday but didn't so I had to call them back on Wednesday (oddly enough he said they had a call back scheduled on Wed evening).

I had to reexplain the problem to the guy and get him to do the investigation for me...again. Says he's going to try to get in contact with the district rep for the my area (MN) and find out what to do. The guy isn't technical but says everyone he talks to thinks it's a programming bug somewhere.

He's now supposed to contact me tomorrow evening with an update. Hopefully I don't have to reexplain the symptoms again.

 

Ok I have access to an updated TEC2 to try and update my Stage reflash with the new TSB files, but I cannot find a way to reprogram. At Hyundai we use a Hi Scan similar to the TEC2 and all I have to do is pop in the reprog card with the updated reprog file and the upload it to the PCM.

 

So I finally heard back from the Chevy people and they are saying that a software patch is needed for a flaw in the ECU (I think that's what was reflashed) code. The customer service lady said she doesn't have an ETA for this, so I asked her to find someone who would and let me know how long I have to wait for it.

The good thing is that I haven't had this problem pop up again and I've been trying to reproduce it more often now. It seems to appear under certain circumstances.
