Just wanted to say hey. I look forward to giving and receiving tech info on the forum. Speaking of which I just put a 3.5 pulley on my 99 gtp and it made it slower. It surges real bad and backfires at 6k before shifting to 2nd. I am afraid that I have a bad KR problem. My mods are a 180 t stat, 104 plugs, Ubend delete, moded airbox with K&N. Any Ideas?
