I contacted John and he told me to send him the tune and they would make another one for me. And all at no cost. Thanks for the info Dark Halo. Hope the program does something for me!!

yea i got a custom tune from Johan as well. I need to get back with him and get some another tune but the one that came from him was pretty good. I had to lower my spark a bit to help with my ltrms from going positive.
Don't forget when you get your tune back from him, you have to go in and raise the shift points and shift speeds along with line pressures. that fudged me up the first time i went to drive.

What did you raise yours to? Did he tell you what to change when you got the tune?

after you get the tune, change all your shift tunes back to how you want them. when you get the tune they will all be like stock. so speed up your shifts and firm them up as well. also, change the shift points.

What are the good shift points and how firm is it safe to go? My Predator should be here this week so I will be playing with it all wekend.

i set my mph and rpm shift points. i do believe mine is working off the mph. i have it shifting at 43 or 44 mph which is about 6850 rpm from first to second. i think at around 80 mph and 6900 rpm for the second to third gear shift. this is with 3.73 gears also.

i had mine firmed up all the way but backed it down to about 22 percent on all shifts vice the 25. also, i had the speed set for -25 but changed it to -22. the tranny doesn't clunk any more during normal driving now.

i got a tune from Johan also, but it didnt make me ET's any better in the 1/4 mile. i played with the stock tune a little bit before i got the custom one. so either i played with the right stuff or the custom tune didnt do anything for me. just my 2 cents
