i can't remember if the ks cel will put you in limp mode or not. if you go chipped p28 then i can disable it. let me know if you want to go that route...i've got chipped p28's or can chip one if you already have it, but then you'll need to get a conversion harness too (96-98 obd2a-1, 99-00 obd2b-1...get it from www.boomslang.us).
