I have a 2001 GTP. I installed an xp cam with 130 lb springs with a full size intercooler and a northstar tb with LQ4 maf. I decided to switch to a turbo, so im taking the intercooler off and swapping to an N/A L36 intake manifold with an L36 tb and maf. I also have 42 lb injectors. I'm changing the intake because the supercharger lim has been ported too much to seal to the supercharger and I'm switching to a turbo anyway, so I would like to be able to keep driving the car until the turbo goes on.
Can I just reset the tune to an N/A tune with a different IFR for the 42's?
Would I be able to get more timing advance than the normal N/A tune?
What would be a better way to do it?
