I'll back you up brian, it was my car! 6500 rpm stage two.
Fixed thank you!

 

To the op I don't mean to jack your thread. But question. Stg2 boosts at 15 right. When does it get to 15psi? Cuz on my car it gets to 15 at like 6k rpms. Anything before it is at like 13ish 14. Is this normal?

If not what is. And how do I get it to normal?

 

When my car was on the GM Stage 2 pulley (77.9mm / 3.06in), it would boost to 12.5psi when I got on it, then build to roughly 15.5psi at 6750 rpm - 7000 rpm. So your boost levels are pretty normal for GM Stage 2.

 

Ok well maybe it was cold outside when I was on it one day. Cuz I remember seeing my boost at 15 as soon as I got on it and it went slightly to 15.5

 

I did and it seems that you and another person seem to the the only ones that have seen this. That doesn't really say much becuase it could be becuase the dealer did not install the correct calibration. What makes you so sure that the car you came across truly has the GM stage 2 calibration?

 

the serial number i ran in the gm system.

rokon owned the car.

 

actually my friend a gm tech over here in tx actually told me that stage 2 were calibrated at 6500 rev limiter now.. yea i was like that sucks thank god he has hpt for me to mess with my car and all lol

 

well how long ago did this suppose to start? Cuz i got my stage 2 installed a couple of weeks ago and my rev limiter is 7k

 

As we have stated... this happends on certain vehicles.. we are not sure which ones...

This is just a few pages back.

 

This is bad news for Stage 2 owners.

According to the dyno test I did on my car when running against a new SS/T, I was making 220whp at 6500rpm, 227whp at 7000rpm (chart below only shows to 6800rpm, but Synapse Motorsports confirmed that my car peaked at 227whp):



A 7whp loss is equal to about 10hp loss at the flywheel.

Yccch ...
