440cc injectors w/ JECS MAF? Please help.
Ok, so here is my situation i don't have enough money for a tune but at the moment i am probably maxing out my MAF, here is my question, i have an ej20g swaped 93 leggacy and i have the grey top 440cc injectors on the car w/ td04 TBE and intercooler, i am currently running at 14-15 psi and i am in need of the JECS MAF but i know that it causes it to run lean, i have bigger injectors though from the ej20g and if i do the grounding mod and put the MAF on will i be able to get by w/out hurting my engine? i am probably running rich right now so if i put the MAF on will it kind of even out my car? please let me know guys this is greatly appreciated!

No...is the quick answer.
Why? I wouldn't trust the ECU to properly run the JECS MAF @ ALL points in the fuel tables. You don't want to 'get by'.
Why do you think you're maxing out the MAF? RU logging it? If you are, just turn the boost down a couple psi.
Ru guessing @ the 14-15 psi? Or running a boost gauge?
You must be running an FCD, too?
Please, just save for a tune and don't risk it....The tune is a very important part of keeping your engine safe.
Do some research on running just the EJ20G ECU. I had a Z4 (13psi) in my Legacy and it was running great when I sold it. You'll also need either Rob's 4-2 Ignition converter or make your own from info on here.
