i just tuned my truck with a intune i3, what a difference it make, tune so far is
diablotune (i run with 93 octane)
15% trottle boost
dod on
trans firm shift
i love the firm shift for daily driving but the hard shift tune is way more fun (maybe need higher wot rpm shift)
i think what i will do is leave the firm shift on and change the parameter on the tow haul mode for harder shift and higher shift point at wot but how high can i put the pressure to match or to be firmer than the hard shift tune... and what wot max rpm i should put
