I had an edge juice and i took it off some monthes after my truck would idle up to 1000rpm to1200 the only way i could make it go back down to 750 was to put it into gear and let off the clutch while pressing the brake, then the other day i was on a three hour trip and i down shifted to fifth gear and my truck was surging bad when i downshifted kinda of like it was hitting the rev limiter this only happend that one time then the worse i bought a tst pwrmx cr installed it and the idle surge was worse it would idle real high and then really low and sound as if it wear gonna almost die and if i put it in first or second gear and took off it would actually rev it self up and go faster without me touching the throttle it missed really bad this all happened even with the chip off DC said there was nothing wrong and no codes in my truck before i installed the tst i did check all plugs were good i took tst out and the problems i experience with the tst where gone still it idles high is there something wrong with my tst is there something wrong with my truck DC says its fine but during that trip it felt low on power and really missing bad but cleared up the next day and hasnt happened since please help
