Good catch.

And good point.

 

shame ya don't have anything to base them off of.....nice numbers though....I'm stock so I can't say much.

 

read, when Doug finished my car was at 27psi. At 21psi I was making 343whp and at 27psi I am making 359whp. Also the turbo does not surge at all. I P&P the compresser side, I'm not sure if that helped it. Thanks to everyone for making me fell better about the HP numbers. But, I see a EVOFPGreen and Revolver cams coming soon.

 

Interesting about the boost and lack of any more major gains between 21lbs. and 27lbs.

This same scenario was encountered with my car when tuning the 20g-LT. It made 366 on pump at 25lbs and only 380 at 30lbs on C16. It was here that we were at a crossroads in dealing with the stock ECU and flashing. The motor was making so much "noise" that the stock ECU knock sensor was the issue.

We opted for an AEM and ended up with 412whp on C16 at 28lbs.

-Disclaimer- I am not a tuner and don't really know anything about it. It's kind of like witchcraft to me, I'm merely regirgitating info from David Buschur. I thought that may be helpful for you though.

 

^^^ That is very interesting.....
