David tuned my 01 Sierra with a single 78/75 5.3/backed by a 5 speed,I had delt with many other tuners on this truck,once I found David the truck finally performed as it should,there was no give and take,no hard start,no problem keeping it running at idle,the truck fires up and drives like factory with much more needed power when laying on the skinny pedal,I will continue to recommend David for anyone that ask me for a tuner.
