Just as the title states, im looking for the pros and cons to going with one of these choices. The most obvious one is price, as a shop will charge 400 but i can get a tune from frost for 200. Ive got a 02 z28 with stock internals, intake and heads but i swapped out the cam going with 232/238 .595/.601 115 lsa. I also added a d1sc @ 8psi with a front mount, 60lb injectors, and 255 walbro. I have stainless works longtubes, no cats and slp loudmouth II. Roughly how much power can i expect using speed density and what could the power differences be between going to shop or doing mail order??? I know thats alot of info but any input is appreciated guys!!!
