I did wonder.I wasn't referring to you as a fuddy duddy...
Unfortunately yes, I basically trashed my box with my home brew tuning mods, and the synergy.
My FL1 was pretty quick too, well is was until the box went pop.
I could accelerate hard enough up an 18% hill, with 1.6 tons of trailer on the back, for it to select 4 gears, and lock the TC clutch in 4th too. Unfortunately when it locked the TC in 4th while I was flat out, there was a grinding noise as the clutch engaged, after which it shuddered when locking.
Andy has also just changed his TC, as his started shuddering when it engaged, and his is still in standard tune, so these auto boxes don't take much to trash them.
I call it tuning on a shoestring.Ghetto decat, tuning box, home-brew straight through...That's definitely not fuddy duddyness on the previous vehicle.
