I am in the midst of swapping intakes and throttle bodies with a 7th gen Maxima, they are a direct fit because of the same engine.but aside from that the numerous bolt on mods I've done. What I am asking is for a tune to take advantage of these mods. I have the Typhoon K&N intake with a bigger air filter, Maxima intake manifold and throttle body, Throttle body spacer, JET chips MAF sensor, Gutted precats. I plan for upgrading the coil packs to Audi R8 coil packs and add a high flow muffler and y pipe Catalytic converter. Looking for assistance in the tuning department.
