SCT Tuned trucks....6th (T/C locked) down**** to 5th/

Does anyone else have a problem with their custom tunes when they are cruising down the highway in 6th with the TC locked and try to downshift?

If you jump on the gas nothing will happen for like 2 seconds and then all of a sudden it will shift and buck like crazy. Really annoying and want to get this solved...

What size/brand are your tires? I would go look on your tire makers website, and find the correct Revs Per Mile (RPM's) for your tires. I''ve heard that many vendors are way off on their RPMs. So check that out and change it on your SCT.

Many people, after changing this, have noticed quicker downshifts.

Yeah I just did that last night. It helped in all the other downshifts except for the 6-5.

You try pressing the od button? When I'm in my xtreme street file and start climbing a hill I will push it and it will downshift.
