superchips 1704-A 3-4th upshift problem
I have a 1704-A on a '05 F350 and when in the high performance tune the truck will not up shift to 4th unless I let off the throttle. I have had this tuner for a while now. #1059752. All other tunes up shift fine, but the high perf one. Whats up? Bad tuner? Bad tuner flash?

Thanks. I thought I'd call them this week. I also thought I'd post it here and see if it was just me or something "known" that I'd had missed. Where can I look for the cal code on the '05's? Not sure if it will matter as I am going in for the reflash and stuff for the recall notice. Maybe the tuner will work better after my truck is reflashed?

I have the 1704-A on a 2005 also. No problems on stage 2 but when I switched to stage 3 I have been unimpressed to say the least. No noticeable change in performance and the transmission doesnt go in gear right away. When going from drive to reverse you can drink a cup of coffee waiting for it to engage. I am considering a change to the Predator even though I will be giving up HP in stage 2 (used when I tow in the summer).
