What MAF? -Speed Density!


The speed density rom originally came from a v8 group-n car that uses a restrictor. Give the carberry SD a try with the original VE map from the group-n car and it should be really close as it is the exact setup you have.

its running super rich at the moment, and with the maf unplugged it idles great , maf plugged in it goes all over the place. already switched mafs and o2 sensors to check if they were bad but all is the same
