I have installed a Comp 206 212 in my '00 5.3 . I already had gibson headers and exhaust on it. I want to get a predator or pcm tune maybe from Thunder racing. Which one would be better or would they be pretty close to the same thing? The truck seems to do O.K except for idle that wants to hang around 1200 rpm for about 10-15 seconds after coming to stop or coasting because the dealer I brought it to cranked up the TPS voltage to compensate for the idle roughness. Any help or opinion would be appreciated.

 

Is Thunder doing custom PCM work on the trucks now? What kind are they using? If they are using LS1Edit (then they are the only shop I know that has the unlimited version for the trucks.), then go that route. If they are using Ed Wright, I would go with the Predator. The reason I say that is because wth shipping your PCM to Ed Wright, your down until you get it back. With custom on site tuning, they can hook you up on the fly as with a Predator.

 

I don't know much about Edit and maybe TR can't do it, I suppose that I'll be going with the Predator after all. Anyone know the cheapest place?

 

Tbyrne. most predator dealers sell them for $419 but tbyrne.com give you overnight shipping and a hypertech thermostat of your choice free.
