could be somthing wrong with the boost bypass actuator ....do a boost bypass-bypass and see what happens .

 

Go back to the dealership and request ALL of your old parts back. Those are YOUR parts, you paid for them when you bought the car. If they say that they don't have them anymore, then tell them that they need to buy you new ones.

Those injectors, pulley, and belt can catch you a good pocket of money if sold... among other things.

It's not "Bad"... but it isn't "good". You aren't going to blow anything up... but you aren't going to be running as good as you should. Just stay out of the throttle.

Call GM to verify. I think they are talking out of their asses. KEEP YOUR INSTALL RECEIPT, if GM says that it should increase the Rev Limiter... then report the Dealership for a bad install (aka being idiots).

 

yah problem is I can't find the right number.. i've tried a couple but they have no clue and don't know who to transfer me to

 

Did you call 1-800-263-3777? That's the Canadian Customer Assistance Center.

Ask to speak to someone KNOWLEDGEABLE in GM Performance Parts or GM Accessories.

I'm almost 100% sure that you should still have a 7k redline.

Take it to another dealership and ask to speak to the Service Manager. Take your paperwork (ie Stg2 instructions, receipts) with you. Tell him/her that you suspect the other dealership of doing a bad install. See if he /she will work with you, he/she should.

The main thing to check, obviously, is the Flash. Just ask him/her if they will check to make sure that you have the Stg2 flash registered to your VIN #, and if so, to make sure that it is indeed on your car.

If all else fails... find someone with HPTuners that lives near you.

 

First off, I had my stage 2 put on 3 months ago, and the redline definately went to 7000 rpms. The boost is around 15 psi peak.

Secondly, just measure your pulley size. It should measure in at 77.9mm.
here is all the info on stage 2.

If you hit 12 psi at 5K RPM then you are boosting sooner than stock, It is VERY possible that GM's latest update for the reflash allows earlier boosting, but levels off boost once 12 psi is achieved...

 

Boost By-Pass mod will tell all.

 

The stage 2 should go to 7000 i was wrong saying 6400; the boost max is 14.5 @ 7000 and max power is around 6500...all this on css.net faq

 

possibly a bad boost gauge, dyno that bitch

 

I don't really know how to do a boost by-pass but i will look it up and see what I can do. I found a shop in town the works on supercharger's, so I will see what they tell me and I am going to have them dyno it to. So I should find out tomorrow I hope. Thanks for all the help everyone. I will post back with what was wrong if any thing.

 

my stage 2 was installed last week and i hit 14.5-15 PSI pretty much from 4500 onwards in 2nd....

and as i mentioned previously though.. my rev limiter is still 6450..

i'm confused too

 

i hit 13.5 with just an intake lol...get that checked out again... sucks man

 

Lol at least I'm not the only one.

"i hit 13.5 with just an intake lol...get that checked out again... sucks man"
Some people have all the luck I am getting it looked at by a supercharger shop in town and plan on taking the bill to GM when they find out whats wrong.

 

One more post on this from me and thats it. If there is air in the aftercooler system, you wont get full boost if the Inlet Air Temperaturet is higher than the ecu algorithm permits; as one poster said the inlet gasket can be put back wrong it happens a lot its an easy mistake. If you dont fit the larger remote reservoir you will NOT get maximum stage 2 performance expecially in hot places like Texas...please stop slamming the dealers, they dont get allowed enough time flate rate to do the job like it should be done and you folks dont want to pay straight time...and as peak power is at 6500 frankly using 7000 is a waste so dont cry....good luck Barhi send me a PM if you still feel you are in trouble and I can refer you to folks in Texas who can help u depending where you live its a big state....

 

Thanks man, I am not slamming the dealer to hard but I did pay over $300 for them to install it. So am not to happy with them, its in the shop am the moment so time will tell.

 

Dude that suck I just got my stage 2 as well i'm hitting at least 16 to 17 psi with a cai. But as another person said on this forum the rev limiter is still at 6500 rpm not 7000 rpm. I'm not sure if there was an update to the flash or what but I have read other people who have had a problem with it as well.

 

I had my stage 2 installed only 3 weeks ago. My rev limiter is now 7000rpm ? I'm not sure why they would change the rev limiter back to the 6500rpm ? It's deffinetly something to look into for sure.

 

BY the way the stock tach needle lag is pathetic, like most analog gauges in most cars, so i put in the OEM optional RL shift light ladder tach (way kewl) and i dont have to look anymore at the needle it doesnt matter. and shifting at best power dropping to best torque when you shift works best, so 7000 is a waste . But i can adjust the shift lites if i want! I think even if the new flash has changed down to 6500 its ok. The main thing is Bahri wants his boost and he should have it...hopefully all will become clear soon and he will be a happy camper good luck in texas...i sure hope the car isnt running high IAT's and that why he cant get boost...

 

a local guy has just offered to scan my car with hptuners to see whats up with this "new" flash and find out if that is the reason my rev limiter is still 6450...

there seems to be a few more people popping up with recent stage 2 flashes that are stuck with this 6450..

i'll post the results as soon as i get them

 

Wrong.

My Intercooler Pump went out and all the coolant boiled out back in October... I went from hitting 16 or so psi to hitting 18 psi like it was nothing. The higher the IAT's... the higher the Boost Pressure.

 

wow that amazing. I guess if thats correct we should all drain our coolant and get max boost? I assume you have something other than a stock GM cal 'cause the protections are built in by GM and what you describe "aintgonnahappen.com" ...time to leave this thread...

 

I was hitting full boost... BUT the protections that are in place on the ECU are to pull timing not boost. My car was pulling timing like a MOTHER.

And just because you are pushing more boost doesn't mean that you are going faster.

 

UPDATE**

I still dont have it fixed everyone keeps saying the same thing "their is not a problem". They have checked for leaks and what not. By-pass valve is working fine so I really dont know what else it could be. One more question for you all. The new flash that we got for stage 2 does it have any thing to do with moving up the max boost?

 

the ecu dose controle boost, thats why many have said to bypass the bypass valve...its not a case of if its not working...its a case of if it is working.


the best way to tell if the ecu is limting boost is to bypass the valve...if you do that and you see more boost...then you have your answer.


how too...for the satrun fourms

Plugging the line coming from the Intake Manifold to the solenoid and leaving the solenoid nipple open to the air.

what it lookes like stock

what it will look like after.


im not saying to keep it like this, im just useing it as a diagnostic tool....now go out and do it...un-plug the line from the solenoid , and stuff somthing in the line just for now ...and give it a drive ....

if it builds full boost ...then eather the ecm is limting boost for some reson, or the acutuator isnt working as it should.

if it dosnt build boost...then you can elimnate the actuator ,and ecm as a problem...then you can move on to the next thing.....simple prossces of elimination

 

Update**
Got the problem fix, it was the boost gauge that was bad. I had a new one installed and i'm at about 17psi WOOT.
