It ran good except for the fact I had Street and Performance in AZ burn the chip which I had problems with. I was going to get it dynotuned, as thats the only way to go. It didnt cost me that much, 300 for a harness, 100 for a pump and 200 for a chip, and misc stuff like fuel line, brackets, coil air filter. You can find complete TPI setups for under 500. You could probably get it done for under a grand. I put 800 Miles on my TPI since I did it back in 2004, now im parting out the truck.
