yeah you don't need a map sensor, you need tuning so you can tell the ecu that that diameter of the throttle body has changed...your idle is probably all ****ed uop.

 

Ok thanks but im looking for a reflash or some ships for the ecu

 

If you did all that you need to add fuel, and messing with sensors wont help. if your car is running lean changes your injectors out with something bigger that way the ECU thinks it is adding the same amount of fuel as it was before but in reality you will be adding more... I would go green tops to avoid putting in a new fuel pump. the ecu should be able to average those pretty well. As far as going any faster don't count on it without a tune. you could always wire in an smt -6 and try to trick the ecu into adding fuel with a different MAF and MAP voltage. Just a though, but I agree with CRANS needs a tune.

 

So like how injector I will need

 

At this rate I forsee a blown engine very soon -_-
