Low and behold.... after restoring and getting an oil change from Chevy, I returned the same tunes to the vehicle. Only this time, I figured that I would modify the Firm Shift Tune and "TURN TM ON"... yup you heard me right... "ON"!
All I can say is... Got TM!?! It's what ya been missing! I promise you; I dare anybody with a similar set up on their L99 to "TURN TM ON", go full throttle, and see what happens!?! Your gonna chirp 1-2, do it again at 2-3, and scratch 3-4! Crazy thing is that the shifts literally feel like your be fired from a sling shot!!! I don't know why or how for that matter? Hell, at this point, I don't even care... all I know is that if you turn it "ON", you better hold "ON"!!!
I've been in disbelief all day, even figure that I must have read it wrong... so I turned it back "OFF" just to be sure? To my surprise, the shifts went back to what I was accustomed to... Don't get me wrong; they were still nice, but NOTHING like I had just experienced! So what do ya think I did.... Yup, turned TM back "ON"... I just wish I'd figure this out a year ago! All I can say is "GOT TM"?!? Turn it "ON" then chime in... you're gonna be sick about not knowing! Can't even begin to imagine what the Hard Shift with it "ON" would be like... and don't intend to find out...
