I'm going bigger turbo down the road but I'm having problems with my car and we can't decide if it's the injectors going or my stock fuel pump isn't keeping up so we figured we'd kill two birds with one stone using the BMP pi kit that comes with 750cc injectors

I think you should fix the original problem before you start complicating the system further, start from a 100% functioning car so you won't have any bigger problems later, the headaches could be huge. If the injectors are the issue then port injection will only be a temporary band-aid, it'll keep getting worse.

with stock turbo, i have never read that it is limited by lpfp or injectors. usually is the hpfp cannot keep up once ethanol is introduced like e30 and running 'stage 2' ots tunes.
can you post logs and describe the problem you are having.

https://www.bootmod3.net/log?id=5fb8...729b0be1c1ae79 https://www.bootmod3.net/log?id=5fb8...90c64d73a0a612 These are the last logs I took and this was a while ago. Basically since I swapped what I said up there^ I've been having a misfiring/studdering problem and it wasn't horrible but now it happens every second. I've tried getting custom tuned, swapping some parts oem and getting new ones as stated above. All types of tests have been done, nothing shows and barely any codes except for a few lean codes |
