Wich MBC you guys use and it has no problem!
I already spend 50$ i don'r spend another 100$ and end up with the same problem!

Plz help

 

If your car is an '04 DO NOT USE AN MBC. You may kill your engine real quick....things that work on the '02-'03's KILL '04's

If you don't have an EGT gauge---DON'T USE AN MBC either.

 

get gauges
get reflash
don't get mbc

 

I can attest for the no MBC with an 04. Mine ran like **** with it. Pulled timing everytime I hit the gas which made the car slower than stock. I since have given it away and ordered an Access Port. Should be here in a week or so:banana: :banana:
