Edit: Wow, dont hate me its 1:05 am and I can't believe I fucked up twice. Wow M6...A4....Im a retard...I dont know what Im thinking...It's an A4...I know Im a jackass

And my car is a 2000, I know it doesnt matter whatsoever. Please make fun of me in the posts for being a retard.

Im buying some new gears soon...and i have watched a couple of vids on 4.30's and it looks like its the best choice for me. I either want 4.10's or 4.30's on my TA but the 100 rpm difference really wont effect my gas mileage that much. I have a few bolt ons, some head work, new camshaft, and new exhaust. I haven't put it on a dyno, but i probably have about 400 rhp, i dont want to estimate too high. What type of gas mileage can i see out of this setup. Is it gonna be too much for the streets. I mean you get it up to 150 in like 20's. And i'm putting niitos on so ill have traction. But still. Any opinions or suggestions? I just want to beat anything out there with the fewest amount of mods to my car.

And Im sorry if this question has been posted a million times before. And thanks in advance.

 

unless you running a tall *** slick and only racing from the dig that's a lot of gear to pull with an auto
