This is why I don't run DSP tunes... Load the big tune, watch the gauges, adjust the throttle as needed:D

Same here. I only run 1 tune. KILL.:happy2:

x3, keeps me honest and things living longer. god only knows what would happen if I had the race tune on a DSP2 switch... id be at Mikes once a year and buying tires once a year as well and that's on the cheap end of my assumption :roflmao:

I've seen a fuel filter change help before as well. But you'd have noticeably reduced performance all the way around with a fuel filter clogged enough to effect the shifting.

I've also seen a spin-on trans filter cause some erratic shifting patterns when clogged up but it wasn't intermittent, it was consistently schitty shifting.

he ought to throw a P1093 though for a fuel filter unless its been blocked.

Mine never did. :D But to be honest it very well could be set to not report in my tune. It's been years and I can't remember. It's good ol' DP tunes from early McRat forum days! DP120 is still my best daily driving tune. I'd like to have a more refined and more powerful tune than his "500hp" tune though. It's still the most potent thing I have though.
