well I ran a 328.5 HP 345 TQ for my first run air/fuel was 13.1
Sec run 331.8HP 346.5 TQ now i lean it out to 13.2 and left it their.
Now before I install with the help of some friends my LT/ and catback exhaust, I dyno @ 289HP 320 TQ
Now thats a gain of 33HP and 26TQ
So do these # sound about right for what most people are getting out of their Z's with LT?catbacks?:D

Help, I'm not sure I understand. Your pre-LTs/catback run was 289? and now you're at 331.8?

I think that's what he's saying?!:think: Except you said a "33 HP gain", which would mean either 299 HP before, or only 321 HP after?:confused:...................I see your confusion!;)
331 HP and 346 lb-ft torque sounds good to me though! Also, I'd like to think that you can actually "feel" a ~30 HP increase!:cool:.

No he wrote it backwards... it took me a few to figure it out as well...
"Now BEFORE I install with the help of some friends my LT/ and catback exhaust, I dyno @ 289HP 320 TQ" before 289HP 320 TQ

yea sorry some times the mind goes faster than the hand.
before my LT and catback I dyno 298HP and 320TQ
those numbers were with the air lid/K&N/MASS air
now with my LT and catback I dyno 331HP and 346TQ
the gains i believe were 33HP and 26TQ with the LT/cat back.

Ah, 298 before!;)
331/346 = good dyno numbers IMO!:thumb:
I think I need to slap my car on a dyno one day!
