Before anyone blames the tune, it seems to dead on the car drives as if it was stock, great idle, light to light, interstate i could not ask for better. to me my numbers seem low any thoughts? Prior to this I had 380 hp/356 tq no heads slightly smaller cam added the ported fast 92 numbers droped to 375 hp/ 351 tq. new numbers are stated above using same ported fast 92. nothing else has been changed same dyno same tuner which i will back the tunner 100%.
Any advice or help greatly appreciated.
