the car at first idled like a cam'd v8 so i adjusted the fuel pressure and got it back to normal...but now the car won't rev past 4k rpms...and if i take it to 4k rpms it back fires real bad and won't go any higher. it's a b18b with a t3/t4 57trim, dsm blue top injectors and a base map off of xenocrons website. slos13 burned the chip for me and b16crxt chipped it for me. i tried adjusting the fuel pressure more and the idle control screw and nothing worked

 

Any CELs?

 

none at all

 

yep...made sure that was right

 

Does the CEL bulb work. Ie comes on for a few seconds.

 

oh yeah it works lol

 

this is the map

B18b, P75, 450's, T3/T4 hybrid, Closed loop is enabled, 2.5" crappy exhaust, intercooled, dyno'd at 213 and 200ft.lbs. at 9-10 psi. This is slightly tuned with much room for improvement.

 

no suggestions?

 

Check the distributor.. like a coil or ignitor failure if you have no cels.
