hi all,

How it looks like in Yours M2? Does the stock Hpfp can handle 420-450 Hp? Did someone log rail presure ?

Rail pressure crashes just the same as EWG cars. Stock tuning pretty much maxes out the rail. If anything if you maintain stock AFR curves in the tune, it'll crash early. It targets nearly 11.2 on the rich end.
