looking at the graph seems like your losing a lot of power up top...

 

It went overly rich up top.On the street it does not do this on the wideband,only on the dyno.

Same with the boost-On the street it can almost maintain maxed out Map,But on the dyno it falls from max(255kpa) to 224 at 6500rpm.

Hope this helps!

 

Hey Andy,

I've tried to follow all of the different posts,
However I have a few questions.
1. 297whp and 354wtrq with the unmodified gm tune and all your goodies sans adm tune, will that power last or will the computer tune out/pull back on those numbers after some time/miles back to 290HP and 315trq (quite a significant difference considering crank vs wheel number comparison).

2. Did/would you get any codes, assuming/if you ran a cat.

 

gm tune unlocks the learn down feature

 

^ What he said, + no codes with cat.
