Yes I was runing on a street tyres and launching at 1200 RPMs
If I lunch it more than that it will wheel hops alot + wheel spins
+ I forgot to switch the power botton ON

To get the factory/magazine test numbers you'll need:
1) an engine running properly, of course
2) minimum 93 octane fuel and enough time for the engine computer to have adapted to it
3) favorable temperature, humidity and atmospheric pressure
4) cool engine (see all the previous articles about heat soak - not an issue for steady-state driving like road course but a big power robber in the first few minutes of operation after sitting with a warm engine)
and finally
5) a lot of practice - there is a very fine line between not enough and too much clutch slip - and even the "right" amount is practically guaranteed to ruin a stock M5 clutch in fairly short order. A couple of "wrong" amounts, where you have engine power on full before the clutch is locked up, your clutch will be toast.
Good luck!

What was your 60 ft. time? That will tell you a lot. What was your tire pressure? Generally you lower the rear and increase the front. I'd bet the heat played a factor as well. From what I've read on the board, the exhaust is not good for any gains. So that leaves the ecu as the only hp gain you have.

Indeed. this plus check you reaction time numbers. You'll be absolutely amazed how a 10th of a second in reaction time gets magnified downsteam. it's almost like compounding interest. I am sure some smart person has a formula but by nailing the reaction time/ stock tires/ cool engine/ 20lbs pressure in rear tires i did 12.97 1/4 mile

Reaction time has no correlation to the outcome of your 1/4 mile time. It only matters if you are racing another vehicle to the finish line. Then it gets magnified towards the end.

Awesome... didn't think about that. It makes sense. But then again I was more worried about beating the vette next to me than my own 1/4 mile time.
