I've been told that low compression pistons like little or no timing advance...is this true? The reason i ask is because i took the car out on some empty highways today and while it was pulling very good, after 5500RPM it would start to fall on it's face...now 160 in fourth at 5500RPM from a neon is pretty good considering i have 2000RPM left till redline but my redline might as well not be there if the rest of the band is useless. I have a mopar computer that already advances the spark, and my cam is advanced only two degrees. The engine has 8.8 compression. Here's all the mods...
96 SOHC with stripped interior CAI, pacesetter header, muffler, no cat, #12 crane cam & gear, magnum head & springs, mopar ECU, 60mm TB, deyeme front mount, EGR block, engine completely rebuilt for turbo
