I just bought the MREV2 + 5/16” plenum spacer. I was going with the headers for my next MOD but a lot of people in this forum said that the MREV2 + plenum spacer would give me way better results. Plus, I’ve also read a lot of good things about the MREV2+plenum spacer combo on rev-up engines. I’m so looking forward to have it installed as soon as I get it. I do have some questions though. Do I need to have my car tuned after the installation? ECU reflash maybe? If so, do you guys know how much a tune and a ECU reflash cost? Thanks in advance for any input! My current MODs are: K&N CAI and Stillen dual cat back exhaust.

 

I would just reset the ECU...you can do it yourself.

 

Just install it and let the ECU relearn itself. No need to reset the ECU. You can't tune the car without additional electronic equipment like a UTEC, FCON, Emange, or Osirius.

 

Although there is no need to reset the ECU as stated, how would I do that if I wanted to reset it?

 

unplug the neg connect on yr battery overnight OR follow the steps on the last page of yr manual.

 

Thank you!

 

ya just let the ecu learn the new mods will adjust in a day or so
