First of all here is my setup: D16y5 motor K&N CAI Ractive 4-2-1 Headers Vibrant 2.5in axleback with a hollowed out cat. So ive done ALOT of reading on this topic. I have a chipped p28 to my (d16y5) but in my reading i guess the vtec engagement needs to be between 2500-3000 i told the guy who did the chip to do 3700. ANYTHING on this subject would be greatly appreciated. Im just looking for options. HX enthusiasts HELP!!! What are my tuning options?
