1993 Eclipse GST
6 bolt JDM Motor
No Check Engine Lights
I am having a weird problem with the car that seems a lot like fuel cut. I had a little fun last night with a GST on the freeway, from a roll in 4th, and everytime we ran, I hit a brick wall in 4th at 5900rpm and had to switch gears prematurely. What could this be? EGTs were never higher than 800*C or so, and the car still pulled and boosted fine(12psi). Here is a list of mods that could pertain to this problem...
Big 16g(only 12psi)
510 Injectors
Walbro 255 High Pressure Fuel Pump
SAFC with settings at zero across the board
2g MAS
Spoolin Up AFPR
Brand New Knock Sensor(6 months old, 4000 miles)
Magnecore Wires(Almost new like knock sensor)
NGK copper plugs one range colder
I have other substantial supporting mods as well, but figured these would be helpful to list in hopes of attempting to diagnose the problem. Could too much fuel be causing this problem as well? I have the B&M FP gauge mounted on the filter, and it shows 46 0r 48 psi at idle with the vaccum hose on like normal. Thanks for any help everyone!
