ahhh, I didn't realize that flashes are based on aftermarket exhausts. I thought they were tuned to the current exhaust setup that's on the car, maybe i'm thinking of custom flash's. Thanks for the clarification John. That's why you're a professional and I am not

 

Again, some flashes can be tuned to your other mods like exhaust, intake, headers, cat backs, available octane rating etc.....I believe it's a good idea to think through what you plan to do........if you decide to flash first, then add other mods, it can be tuned at a later date.

My software is from EVOMSit, they wanted all of my mods so they could tune accordingly.

I am sure others will validate, or not, what I am saying.

PS. Don't over think it

 

Is there any sense in swapping out the turbo's first if so to what? I want something that will still be easily driveable in traffic.

 

If you are stock and want to flash, BUT plan to mod later, make sure the tuner you choose will provide you with future tune "modifications" with some kind of a discount, most do, but ask!!!
