Sup all. Car currently has the 05 dynoflash ecu reflash (not custom tune), a perrin catback, and an HBC @ 22psi.

Friday i'm getting a new megan turbo manifold, o2 housing, downpipe, and test pipe.

I'm under the impression that I won't need a reflash, am I correct?

The car right now makes 262whp/262ftlb 12.3AFR, so i'm anxious to see what completing the exhaust system will do

how did you get to 12.3? his flases are at 11.1! I wouldn't be boosting if I were you.

Wow, 12 afr is really lean...you might want to get it retune. Also, the car will run leaner when you free up the exhaust.

Thanks,

Yea I would suggest going and getting a dyno tune at the very least if you plan on adding those mods are are currently at 12.3 AFR

I doubt your AFR is 12.3 above 3500rpm. Yes, you need a retune for all those new mods.
