Have a 04 GMC CCSB with a LLY, has 105K on the clock with no upgrades. Wanting to know where to start? Was looking at the following. Also what would be the best order to do
Banks Power Ram Air Cold Air Intake
Banks Exhaust
PPE Hot 2 Programmer with Dash Board
Need what would be best, just looking for better performance and mileage
Only getting 16.2 mpg
Also Speedometer quit or works when it wants too, sensor?
Thanks,
Doudad
