Sounds good but remember I want my warranty. I was looking at ZZp's pcm tune and they state that gm cant distinguish between them.

 

correct. I was lucky enough the Tech who did the work is a good friend and allowed me to help him with the install. GM sends the program to the tech which is transfered by the tech's Tech 2 programmer. I can't understand why different dealerships would get a different program since it's coming from the same source.

 

my guess is lets say they might not be able to connect at that time, maybe they have a backup that they use?

 

well that sucks about the stage 2 6500 rpm rev limit. thank god i got mine back in 07' before they did this .... hey maybe you guys can get GM for false advertisement ?!? they used to state the increased rev limit, larger injectors, smaller pulley, and the tune .... i would be madder than hell if i didn't get the 7k rev limit ..... it really helps keep the car in its sweet spot.

 

gm stage 2 people.............do any of you have a flutter between 6500 and 7000 rpms? And if you do what supporting mods do you have?

 

only thing other than the GM Stage 2 I have in my car is a K&N filter (yes filter only) and I dont have any flutter. Then again I've only taken it that high twice, once on the test drive and a day ago after this post was created to make sure I wasn't crazy lol.

 

hmmmm..... I never got a flutter either. I wonder why people are experiencing that?

 

07 and older gm really can't pull the numbers to compare them. they can tell how many times it has been flashed, but not like the tattle tail as the 08-09's have

 

GM Stage 2+ here .... no flutter between 6500 - 7000rpms. she bulls like a bastard up to 6900 rpms or so before i shift to miss the limiter .... i have a cold air intake, extrude honed exhaust manifold, and redline water wetter in the h.e. (<- if you really wanna call that a supporting mod). try doin the air box mod or some exhaust mods .... your car might be choking up top .... if that doesnt help, your tune maybe off.

 

If your car is "almost bogging" on the 1-2 upshift, you need to work on your mad shifting skillz yo, lol. Bone stock with no mods at all and no reflash it should break the tires loose hard enough to induce occasional slight wheel hop on the 1-2 shift - I know mine does!

The 7k limiter is definately better though; keeps the car in the peak of the powerband through each shift (so worse spin into 2nd, lol) and even better - and totally indicative of excellent planning on GM's engineers part - are the ratiosvs 1/4 mile traps. ver notice how stock the car finishes RIGHT at the top of 3rd, can't quite get to the limiter before the traps? Add 30 or 4o hp, and you'd need to grab 4th, costing you a tenth or more... But Lo! What's this? They raise the limiter to exactly what 3rd needs to be at to get through the lights without another shift! Brilliant!

I bet it varies by VIN. That's the only sensible reason for some people to get the 6500 and others the 7k. And if GM knows that some cars have an issue revving higher and they know which cars, then they know what's wrong, and they know they don't want to fix it under warranty.

 

That is a very good idea..

maybe pre warrentied cars are getting lower rev limits?

i think there would be a issue though of who gets to decide that...

 

Pre-warranty is another excellent bet. it's either that, or as I said - specific vehicles on a VIN black list.

 

what do you mean by pre warranty?

I do know they required the VIN for the program, however I just figured it was to ensure you get the right updates as is anything done to a computer.

 

I could definitely spin the tires in 2nd when stock, but when they grab there was a noticeable lag until it got further into the power band . I've been shifting for 20 years ...so i can bang a gear as good as the next guy. Although no amount of skill can make up for the large gear ratio gap between 1st and 2nd in the F35 on the 6500 limiter.

 

Oh for sure it's 300 or so RPM shy of where you'd want it, but "bogging" has a different connotation to me, lol.

 

i installed stage 2 like 2 months ago and have the 7k redline

 

The rev limit on GM Stage 2 is 7000 rpm.

 

pay attention to the rest of this thread. NOT ALL OF THEM ARE 7K

 

no sir they WERE ALL 7000K until gm decided to change them to 6500 because of warranty issues I BELEIVE thats what my friend told me, he is a tech for gm so yeah

 

for further proof if needed. i have a file from an ss with an s2 deal on it. it was 6500.

 

lol theyn should need no proof lol so many people here telling them that some are 7k and some are not should be enough haha but yea u never know with people these days lol..

 

When did this happen and which version number of the tune did this start with? How many different tunes does GM actually even have for the stage 2 kit?

That sucks since I was going to get my stage 2 kit installed next month. Other than using something like HP tuners, is there any way that one can tell if the stage kit tune has been even installed correctly from the dealer? It seems to have been common in the past with dealers not installing the flash correctly, and without the 7000 RPM rev limiter it seems it will almost be impossible to tell if it was done correctly.

 

there is more than one tune per year. updates and other things

 

Can anyone who is om here and is a GM tech truly confirm whether or not the rev limit has been decreased to 6500, and if so when did they decrase it? Not trying to sound like a ***** but I am not believing this. I do not understand why they'd reduce a rev limiter becuase stage 2 is continuously making power up to 7000.

 

read the rest of the thread.

i'll be more than happy to post proof of the stage 2 map i have for the car in illinois
