Apexi neo help.

[RB'ds13]

Hello, i am just finishing up a rb20 into a s13. ive done alot on my own with help from the internet. today i took the car out for the first time and it started up idles fine but hits a wall around 4k(while driving) and starts cuting out a little after that. i will have my wide band hooked up tomorrow and my temp gauge(welding bungs for both) . Im only running a down pipe so i know some of my problem is comming from that. As far as the neo goes i have it set for my maf 2-4,im running a z32 maf only because my swap didnt come with maf or maf plug and i was able to get a z32 maf and plug for free.

i have never messed with a turbo car before and am new to this so any more help with the neo would help me. i will get it tuned next month when i have the money but i need it to run ok for now so i can get to work and school.

is this 4k on the stock tach or 4k on the neo?
if its on the stock tach your maf wires are backwards.

it. around 4k to 5 k for both. for the maf i have it set 2-4 then its set single-single idk if that part is right. oh and i was able to set my tach close to what it should be. when the maf wasnt hooked up it wouldnt rev up at all so now i know its something different still dont know if its hooked up right but i followed a diagram the best i could. THIS IS the FIRST time i have made an account to get help with this caR.
