    • Dinan Stage 2 N63 twin turbo V8 tuned F10 550i runs 12.9@112.9

      Congrats to BimmerBoost member @alextremo who took his manual F10 550i out to the New England Dragway and ran 12's with only a Dinan Stage 2 tune. Alex weighed his car with himself in it and it came in at a staggering 4,560 pounds so running almost 113 mph and high 12's on stock runflat street tires along with that weight is certainly impressive. The Dinan tune clearly has made a considerable difference. The vehicle had an 1/8 tank of gas and some MS109 race fuel mixed with pump gas. This vehicle is capable of much more in cooler weather with some drag radials as well as supplementary modifications.

        HUGE +1 for OE Tuning

        They tuned my M3 and I'm in love with the power bump.

        Yes, OE does good work. Their S65 tunes are pretty much the best that can be done on that platform.

        I went to the import showdown at silverdollar raceway today with the idea to just spectate but I guess because of low car count they decided to allow TNT between rounds so since I now carry the helmet in the car I jumped in. Made 4 passes with a best of 13.07@109.40 and a 60' of 2.108. Pretty happy with that as I had 1/2 a tank, I think if I can come back in a few weeks with 1/8 tank and a tire pressure gauge to drop the psi to about 25 I can see a 12.999 pass. Hopefully though next time it'll be with a tune and run mid 12's. Alot of people were impressed with the big sedans time.

        Bumping this cause I think I might have an idea why my power is off since getting the downpipes. It's getting pretty cold in Atlanta and I usually turn the car on in my basement and when it's warmed up pull out. But today I got a low tire warning and stopped at a gas station to fill it and left the car on. Since it's real cold outside the exhaust is real visible, I noticed as I was filling the tire that I had a steady stream of exhaust coming from under the hood. I popped the hood and saw more exhaust coming from under the engine cover. So I guess I've got a leak, not sure if that would cause the big difference in power but it can't be good. I'll see if I can pull the engine apart tomorrow and try to pinpoint the leak. Also while I'm at it I'll see if I can put some non foulers on to get rid of the CEL.

        That could be the source of all your problems.
