OK guys...ive read and read on people saying that one of the first mods I should do is upgrade the ecu...or that it should be on the top of the list. Well What should i really do? Ive searched on this and havent found a for sure answer...i mean people are all saying different things. Im planning on gettin a Turbo back exhaust soon.....would it be ok to run the car with that and not an ecu upgrade? I dont want to F*** anything up because i just bought the car like 2 weeks ago and dont have money for repairs. If i sound like i dont know what im talking about maybe i read the other threads wrong and im a moron...just ignore me if that's the case. Thanks everyone

 

DAMN.....i should have posted in the ECU forum...sorry .....oh yea i have a 93 FD...sorry again about the wrong forum post...im just know getting use to these forums.

 

General rule of thumb is two mods, like some combination of Intake, Downpipe and Catback. Don't do a Midpipe until you have an ECU.
