I go the 87 tb installed on the truck and did not notice any kind of difference at all. The only tune I have right now is the 93 oct. Ill get the hemifever tune and see if i cant get more out of the TB.
I still have not received any of my audio stuff yet
Still waiting on the rear sway to come in and just order the front sway for the truck.
I replaced the revers lights with some leds and man do those things SUCK! I have some bigger once coming in today will see if they are any better. Also replaced the license plate lights with LED. Now those are alot brighter
