Need some help please!
Break down of the car, before i tore it apart to do a custom kit it ran perfect no issues. Now the car (2008 evo gsr) Is complete but i cant seem to figure out a issue im having so im asking for some help. Ill PAY, whatever it takes im this far and don't want to give up.
Issue im having is a installed a complete custom kit, with 4inch intake i bought a 4inch weld on maf plate.. Well got it all together and try to start it and it runs for a few seconds and dies. I cannot keep it running even with my foot to the floor on the gas pedal. BUT as soon as i unplug the maf it runs and idle just fine. I did some reading and have a tractrix 2.0 so my buddy helped my put the maf to the max so it reads off the map sensor and we were going to tune it that way. Well as soon as i plug in the maf it still dies. Ive tried 2 different mafs already. Please any help would be greatly appreciated i will even paypal whoever for help lol.
my setup:
sidewinder setup,
6266
tial 44
tial 50mm recirc bov
4inch intake
rest is stock. i just wanted to get it running, then i was going to put a bigger fuel setup.
Pic of the setup. thanks guys
*If you need anymore info let me know i have no problem telling all i know

You need to scale the maf for the 4 inch inlet . Lots of threads on how to do this. If you choose to run map then most likely you will still have to adjust
Some fuel tables (SD tune) and add a resistor to replace the maf . https://www.evolutionm.net/forums/showthread.php?t=646117&styleid=27
