All these mods with E85 and porting to the msd intake make about 80 rwhp. And I believe it. I picked up .8 and 8 mph all said and done compared to near stock on drag pack

10 rwhp is a joke something is up

Maybe the aftermarket converter wasn’t locking in the Camaro ? It’s trap speed sure does suck for the mods I don’t doubt it
