1-2 Shift Flutter

[RedFX4]

Ya I set the shift points to 5000 on the tow tune and it still revs to 5200 for whatever reason. Yes I selected done after and it re-uploaded the tune but there was no change.

Finally burned off my 88 octane tank and filled it with 91. Retarded the engine by .5 degrees and lowered the shift points to 5000 for 1-2, 2-3 and 4900 for 3-4. Runs like a charm. I really think you need that load of hauling a trailer on the tow tune settings for it to work properly. Performance tune shifts better to. Far less harsh, more like a lightning now.

I'll just run the 91/93 performance tune until I get and custom 87 performance tune from php.

Thanks for all your input "JackandJanet". Appreciate the help. I'm new to the whole tuner scene if you couldn't tell already.
