Really posting for opinions on what to check next...............Ok, I have a b18b running 8lbs of boost, and i am running dsm 450's (with resistor box), wahlbro 255, and a safc, also have fpr with fuel guage and pressure set 41psi. Well today I took my car out with a friend who has experience hack tuning and the car seems to run fine until about 4k rpms and it starts to sputter and break up then ones it gets to about 5k rpms it pulls good. I just installed the injectors today and yes they do work. So my question is what/ where should i look at now to fix this issue. Should I buy a fmu?? And yes i know i need better fuel management(hondata, crome uber etc) but HVAC is slow right now so I am not getting good paychecks. And could my MAP sensor be the reason for the breaking up? <thought MAPS didn't need a missing link unless you run more than 10lbs of boost>?! Opinions would be appreciated................................

 

Honestly, if you dont want to spend the money on actually tuning the car, you would be better off with a missing link and an FMU, toss the SAFC in the trash. "Hack tuning" probably isnt helping you.

Oh, and if you are using the stock (unmodified) ecu, you dont want the map sensor seeing boost.

 

dude,
just buy a base chip from xenocron it only costs 25 bucks and will get you running for now..
