Where did i go wrong
I own a 2005 CTS-v (still brand new) and i installed the followin parts on it
FAST 90/90
GMPP high compression heads
Yella Terra 1.7 rockers
7.4" pushrods
GMPP lifters
LPE GT11 cam
LPE High Flow Oil Pump
LPE CAI
SW 1 3/4" headers
2.5" Ti Corsa Catback
Matrix High Flow Cats
25% UD pulley
I made 367hp on a mustang dyno and well, i am gettin plenty of laughs from my setup and now my numbers. Torque is not available due to rpm pickup not workin...
Should i increase my Valves from stock LS6 to 2.055" and 1.570". The car feels great on the road, and i am gettin a nice mixture all across the board...
Please help, i am actually lookin to shave off weight, but increasin the HP is a nice thought...
Btw my engine compartment is VERY tight so a vararam spacer is out of the question. Rad is in the way.

run the car at the track and see where it mph's. dyno's are for tuning not judging a cars power level. my car which is obviously very different from yours put down anywhere from 315 to 355 depending on the dyno but runs in the 11's @113-116 depending on weather.

I dont do quarter miles, i do circiuts. I have to admit anything above 1000rpm she pulls me back and keeps me pinned right up to red line.
I personally tuned it, i will look at disablin the torque reduction. But i am usin EFILIVE.
Will playin with the perdicted airflow help boost up the power?
i am runnin 12.8-13.1 at WOT

that's bout what my car made on motor with ported 243's, comp 232/236 595/601 112+2.
1 3/4 long tubes 25% underdrive pulley & TR6 plugs for nitrous
Mine made around 370ish with the converter unlocked through a 12bolt.
For comparison.........Cam only my ride made 403 wheel on a dynojet, but that was with the converter locked and it was a dynojet.
don't worry about the numbers.......if it feels good and runs good times, then who cares about the number

dont forget to make sure you are properly tuning your ignition advancing map, that is a CRITICAL part, equally important as the air fuel mix. Changing it also will change the air fuel mix as read by your computer, and could make it look fine or good when it is pretty far off, so make sure you really know what your doing tuning yourself or else you wont be getting the power OR efficiancy and it will look like it is running dandy
