Anyone ever use the M2 stage III ecu with full dp, mp and cat back with full non-sequential turbos with a ported wategate. I know that M2 does not recommend using it with the mid pipe but i know others have done it. I'll be using a upgraded fuel pump as well maybe even a rising rate fuel pressure regulator and maybe a fmic. Motor will be healthy and boost will be controlled by a profec B. Car will be used as a daily driver but will be draged once in a while. And car will be dynoed to make sure its safe, but dont want to wast my time if it wont work safely. Boost will be kept under 14 psi

 

I have it with HKS Racing Ti, Pettit dp, Greddy SMIC, and boost controller at13 psi. No probs so far. You may want to keep it at 13 psi since I think your injectors are maxed out at that pressure, not your fuel pump.

 

I ran m2 stage 3 with m2 large intercooler, intake, dp, mp, dual n1's, NS turbos@15psi, and upgraded fuel pump for a year with no problems. Motor is still running, I have since upgraded to a PFC and bigger injectors so I can run more boost. I never checked the a/f with the m2, ran it hard all the time and dragged it a bit, best of 12.6 with that setup. I was also running a walbro fuel pump, which I would recommend, seems to be a great pump, easy install, and you can't beat the price.

Okay, seems like its been done before so i guess i'll give it a try. I thought the m2 was only good for 13 psi?
