I have an 03 g35 with a few mods. Intake,headers,true dual exhaust, and skunk 2 spacer. Should i get the m-rev or ecy flash next

 

MREV and then the ECU reflash. if you're only goin to get one then get the reflash.

 

+1. Definitely get the reflash if you can only afford one

 

yeah but if you get reflash then later get mods dont you need another reflash

 

why would you need the MREV since you already have that lower collector?

Reflash and

 

How much is M-REV and reflash cost? Will I feel a difference? Can the dealership find out I did this?

 

get the reflash AFTER youre done modding

 

The best thing you can do is get both.

Does anyone know if, lets say he gets a UTEC, modding after he tunes it will work the same as modding before the UTEC? The order doesnt matter right? Even though its more of a custom to mod first, then tune?

.

 

+2

Reflash shoudl be the last thing you do after all your mods. Don't want to have to pay to get it done a second time

 

Get both!! If you only have money for one right now, wait and save up. You won't regret it.
Good Luck with that.

 

I'd check too see if even doing the MREV would make much of a difference. You already have the spacer so your going to receive some port n polish work with minimal gains IMO?

 

Flash it, you don't need the MRev, you already have the Skunk2 5\8, right?
