SR doesnt run right

[Leo'S13]

It sounds like your MAF is not working.

you're really restricting the capability with your larger injectors and larger turbo with that sr20 maf.

picture yourself running a mile breathing through a cocktail straw....

1. do you have some type of rom tune to compensate for your upgraded turbo and injectors?

2. if you don't, the SAFC won't cut it as far as tuning your engine.

3. did you get some type of dyno tune?

you should get the Z32 MAF back on there so everything starts breathing right, but make sure you wire it correctly. there are plenty of guides.

I already had this setup for a long time. And I havent had any kind of tune besides safc. My car is running stock boost and everything was good before. It just suddenly became like that on highway.
