"It will prob decrease boost but keep same power, everything will work more efficiently. When you increase boost you will get a power increase" This makes sense to me, but as I have the haltech interceptor won't that mean I can dial up the boost with a dyno tune? It's currently running 17psi so will be pretty conservative once I bolt on the TMIC, upgrade the FP internals and change the plugs, I was sort of thinking increasing to 19psi would be ok. Or has the haltech now run it's course and should I consider Cobb AP?
Going HALTECH to COBB is a downgrade in my mind... If you have a good tuner with HALTECH stick with it.
Otherwise you will need to go COBB then get someone to modify the OTS maps to get the same power. I can't imagine the COBB would offer much more then L/C and FFS over the HALTECH... the HALTECH may even offer that.
