Default Weird....any comments...

I just put in my TSP 224/228 cam but used my Hotcam tune. I know the change aint to different but my LTFTs in the lower ranges were all in the -10 area. The funny part is for the first time my car could come off the clutch smooth with little gas and no jerking or studdering and feels like its runs awesome. Even the KR was all but gone. When I retuned it, now its all in the 0 to -3 range but my car is back to shitty slow starts on the street with studdering and jerking again. Feels like it almost boggs out at times in low r's and little gas from a start to slow roll. Any clues???

thanks.

lolol. I just redid the Primary and secondary VE table and MAF calibration. But this is the thing. Even with my Hotcam I had that problem after the tune. I got the trims all to -1 to 0 on that tune.

May I suggest you go to an 01' Operating System? You'd benefit by only having one VE table, and more expanded tables that aren't available to us 00', like advance vs IAT for one....(works good on Dry nitrous and FI Cars). Load a entire rewrite 01, then transfer table by table your old hotcam tune, and then work from there....OR just load in the 01' and then start the tuning, basics, VE, MAF, Idle and relook VE, MAF and idle til its good.
