The best way is to datalog it so you can see how boost is running. there might be some dips in a couple runs till meth is running continuously. A couple of runs or pulls you'll be good to go.
Good luck! 
Car looks great by the way! |
I must really thank M6beast for his advice, guess what? While I'm still waiting for my S2 board for meth. I pour VP 100 octane race gas to test out on +5psi & what I can said is I'm freaking surprise with the result. I don't have any misfire or whatsoever experience that I had the last time (misfire on 4 cylinder & transmission problem) the car pull like a bullet train just after a few rounds of adaption. I don't even have to leave it overnight or a few days of waiting.
I'm now telling every M5/M6 owner, this Engine & Transmission is not what u may be thinking of (as of it is very limited) The last time when I hv misfire I was on 4.5psi with 98ron with 1 bottle of +6 Ron booster. I will keep trying all different kind of fuel with different boost. I don't think it will misfire or with all kind of funny code again, the method is very easy just let it adapt. Do it with 3rd gear n 4th gear & DO NOT step on the gas in a short second. Just press it down slowly to run the engine pull to redline n let it feel the pull & adapt to the mix of the AF. Repeat the same thing for 5, 6 times if possible then stop shut the engine for a while like 10, 20mins n start the car n repeat again. After which I can tell u the car will be totally different!
U will not believe till u try it, last night I push it to 5.5psi with race gas(without meth) even higher than what M6beast did on 5psi. The car will just keep pulling......
Heading to the same dynamic dyno very soon, stay tune.......
