So like it says, the shop and myself finished the return system and intake build on my 04. I was running a Steeda CAI and stock fuel system with a MAFia. I was pushing a crazy 23 psi (previous owner did this, I fixed it now). I put the NEXTGEN 12" High Boost intake from JLT and a bigger upper. after geting my 580RWHP results I was ok but not crazy happy because was at 587 rwhp before. Then the details came out. the car was running too rich before today, pushing too much boost, fun to drive but wasnt where it needed to be. Now I am at a beautiful AF range, running 15 lbs... that 15 lbs of boost, and it is possibly the most enjoyable car i have ever driven. i dropped 8 psi and didnt lose hardly any power but have a much safer and more enjoyable car to drive! I am very happy. And the JLT looks great under the hood!
