My 1990 300zx is an average looking Z lowered on coils and on some MB battles (18x9.5) perfect stance for me, Performance wise on my car you can find an upgraded intake, Exhaust (HKS) and some Stillen Headers

. which all should increase the horsepower some way. I know on Z1 there is an ECU tune for there NA power pack. I was wondering if there was another place Near By (Phoenix area or California) that can do the tune around $300. Im looking for like a 40 hp jump from stock, is Z1 the best option or should i drive out to SoCal?
