I live like 20min from LMS and I'd never go back there. With Nostrum's stage 2 kit coming out soon this mod seems expensive and unnecessary. Stage 1 maxes out in the low 500 whp range (turbo limited), and the actual injectors/pump max around 650whp. Stage 2 is going to be at least another 100whp capable.
So are you trying to push higher than that?
I am trying to get into the 700-800 whp. I’m limited to the slow release of new parts and of course the complete unavailability of upgraded internals. I rolled a bearing on pump gas due to leaning out. The dpmi was more of a protection measure for now and future upgrades. I already installed a snow meth injection system and 2.5g tank. LMS didn’t like the setup for reliability. It sprayed before the throttle bottle. I really needed to get it tuned. I was having trouble finding someone who even really
wanted to tune this explorer having already blown the motor and mods they haven’t dealt with before.
Finding this forum maybe I can learn. From my personal research and making a ton of phone calls. LMS were the only ones waiting with open arms and confidence to custom dyno tune my explorer. They recommended this routed because I had the meth kit installed already and said the only way they would tune it is to covert to direct port injection. I’m well over 100k into this truck and no turning back now. I’ll continue to upgrade as they release new parts.
I drove it gently 5k miles untuned to break in the motor. I don’t drive much so this took forever. So after a million calls and a lot of time and really in need of a tune basically LMS was my only choice. The best tuner I know didn’t want to touch it.
