Trans tuning UPDATE - My opinions
So I tried the KAM reset through the SCT but with the key on it said "reset failed" but with the key off it said completed but almost instantly, the SCT doesnt do ANYTHING instantly so I have my reservations whether it did anything at all.
On to my update - Chris from TSD sent me two revised tunes one with early lock and one without. I loaded the early lock as that is what all the other tunes I had use and one of my biggest gripes with the tunes I was getting so I asked chris for one without. Well long story short I loaded it on my SCT and did my little KAM experiment and then loaded the tune. I have not got on it too hard but so far the tranny is shifting silky smooth. I gave it the wood one time and it shifted a tad high at close to 4100 rpm but it banged the gears no problem and seemed spot on. We will see if it continues to stay that way or if it learns how to mess itself up. My only gripe is that I can peg 14-1500 egt before 70mph - I may be out of air up top and need a billet wheel or something to run these types of high performance tunes.
Now on to my rant and my opinion. EARLY LOCK UP TUNES SUCK!!!!!!!!!!!!!!!!!!!!!!!!!!!!! If this has been my problem for the last 13 months fighting all these tunes I will be very disappointed that certain tuners would not listen to what I wanted as I was shoe horned into EL tunes by everyone and not knowing or thinking about that could be my problem. The tranny has never shifted this good on a performance tune since I loaded my first performance tune. Also the truck had a nice lunge to lock then another shifting into 6th gear - that is gone now. So I believe early lock tunes are garbage -- hopefully the truck continues to shift like this and doesnt revert back to goofy shifting tactics.
OH and big thanks to Chris @ TSD for actually listening to what I WANTED and getting me a tune without EL - it has been a couple months since he sent them and I have been fighting the EL tune ever since.
*EDIT* to be fair on my tune from Tony I never asked one way or the other I just ran what he sent. His was a tad harsh shifting but otherwise ok - his tune had power but I couldnt justify the 2mpg loss and the 10+psi cruising boost. I gave up with Tony because I didnt want to pester him as his daughter was going downhill fast and quite frankly my truck and tune was insignificant to the last moments he was going to get to spend with Morgan so I didnt want to be a reason he lost even 5 minutes with her. I would like to have him do more for me in the future though.
