you live in jersey call modern perf. they did my car they work with evosport. nick is the boss 732-222-3679 comp and a set of air boxes is a very nice upgrade

Thank you!

no problem the guy does good work. He is going to do a set of headers for me in the near future and also a crank pulley.

@nv@

what kind of performance boost do you see with the ECU?

I did a ecu and air boxes at the same time and I had them do some little things in the intake side I saw nice gains on the road I have not put it on a dyno yet I am sure its 20whp at least the car pulls alot harder now big difference in the high rpm's its wierd though the car does not feel any different for the first 200 miles or so I think the car has to learn
