Motordyne M370

Because its alot of money for something that does not add alot of power and usually makes you lose peak hp. Your just guessing 10-15 because of the way you think the car feels. Did you do a before and after dyno? I have seen a before and after dyno of this part and it added little gains and then lost to a similar modded Z without the manifold.

i have checke power difference in a different way :X lol in a comparison of 2 vehicles on the road...and i think mid range power is more important than peak...a lot of other mods like intakes/exhaust give u top end but u lost torque..you'll be making some of it up with this...(NOT REAL NUMBERS BUT TO GET IDEA) you'll be faster making 320 from 6k-8k than making 280 at 6k but 324-330 at 8k
