Best tune for 5.3

Post by HEAVYCHEVYDERP »

what is the best tune to select/ build in the i3?

something like....

87 octane Performance tune.
Firm Shift Transmission tune - ON
speed limit - OFF
TORQUE Management - OFF
adjust tire size



i need a check list of recommendations and better instructions.
the instructions that came with it were not good....

I'd like to know if anyone else has adjusted any of the other settings for the 5.3 like shift firmess percentages, WOT, torque management percentages, etc.

i did
i like it.

upped the PSI by 3 and dropped the shift time by 1 second.

1-2 shift is now a solid punch compared to before.
i might keep trying other options with 2-3 & 3-4

the main thing i like is telling the transmission how to downshift.... like: to drop to 1st gear, at 40mph, that way when i slow down to take a turn i can really LAUNCH out of it again.
