My friend bought a new 2004 E46 M3 3.2 Liter 333 hp. At that time I had a stock ECU, K&N filter, Lexus AFM with 550' and a 60 trim with 10deg clip CT-26 and crush bent exhaust with ebay muffler. Unbeknowst to me I also had a mild BHG. I had mbc set at 15psi. We line up around 40 on the street 3 honks I started on top of 2nd and he immediately pulls 2 cars but as I spooled up I was gradually reeling him on but had to slow down due to traffic. One more time the same thing happend. I pulled over and raised the boost to 17 and the third time we go again he pulls about 1 car but I had fuel cut off issue at WOT and had to back off even though I knew i was catching him. I lowered it back to 15. This time we start from about 25 and I was in first gear and I brakeboosted. 3 honks we go. Top of second we were even then I walked him steadily and shut off at about 105mph. He was very surprised and he told me that he redlined it to 8500rpm during the race. He gave me a ride in it and the brakes were forumula one bad ass . And so were the acceleration. That M3 definitely has top end power. I gave him a ride in the supra and he was very terrified at the brutal accelaration. AFter the race I over heated It is now being rebuilt
