Havent done much on the performance side of this truck (besides keeping it running that's hard enough) but just recently got a intune, k&n cai kit and obx 1 5/8 longtubes with cats. Using the 87 with k&n tune there was no option to add headers should I adjust the gas a bit richer and change the mass air up let me know thanks

If it were me I would get rid of the tuner get an SCT and have a professional aftermarket tune built for it
