Dyno Guesses & Bench Racing Forum - What are possible power gains??

Ok i kno theres no way of knowing without a dynometer exactly but what do you guys think my car is doing with the following mods?(2000 Camaro Z28 A4)

Pacesetter LTs
3 inch ORY
4" i-pipe with mufflex 4" muffler
SLP Air Lid
Hypertech Power programmer 3(Engine Tune, Fans at 195* stock therstat, 50% shift firmess,No shift points yet)
Stock 4l60e
Stock 10 Bolt
EGR/Air Delete

Someone told me that only 320HP maybe less because its an a4 but it seems a little low for what i have invested into it. Anyone have similar mods and have a exact HP/TQ reading? also is it true that a4 has reduced hp then a 6 speed?

i think someone told you about right. yes auto's make less, the converter eats up some of the power on its way to the wheels, basically your doing a full exhaust, which will get you around 25hp give or take a little. so your at maybe 280-290 for a year 200 auto. so 325 is generous. because that hypertech isn't giving you much. the lid will help some to, so i agree with the 325.
