hey guys i have a red top sr in my s13. i just recently did the swap and i could never get it going just right. ill tell u what i have done to it. its all stock just a fmic and full exhaust. thats it. stock ecu i am running bkr7e ngk plugs gapped to .28 stock maf. now what it is doing is running really rough at idle. but if i drive it normal it runs 110% pulls really hard just runs amazing. but at idle it runs like complete crap. i messed with plug gap but it runs the best at .28. and i messed around with my iacv screw. i did timming with a light and it ran a bit slower than it is now when it was at 15 deg. btdc. so i advanced it a touch and it runs alot better at idle and at wide open throttle so i left it like this. my tps is set to .43 ish when closed and at wop it is at about 5.03 so thats all set. now the only thing i can think of is a leaky injector maybe. like when low psi it is spitting out but when i rev or drive it it blasts threw... idk. and one more thing i would like to share is when i rev the gas eather with my foot or with my hand on the throttle boddy pulley, it has like a 1 second delay. say if i rev the gas. it takes like 1 second for the car to rev. almost like i have 30 feet of intercooler piping.... so thats an issue too. any help, advice or tips on eather the reving delay problem or the rough idle would be a big help. thanks guys
