Thread: TB options

Im just wondering of us 04+ guys have any TB options since we have drive by wire?

as of right now we dont have one... but it was brought up in the n/a engine forum and blue91 found a similarity in our tb and the ones from the ls4 gxp's and also the ls2 gto's, both would be amazing. tdc seemed to take intrest in it and he may market them in the future but i believe they need to figure out the wiring diagrams and what kind of adapter/splicing would be needed to make them run since they are a completely electrical tb.

Us LS4 guys have them ported by a company in Florida. They also do intake manifold porting. Fasterproms is the company. Extreme TB has been know to set codes with the LS4's but fasterproms has info to change paramiters to make the code go away.

i cant speak for the ls4, since some company does them apparently, but i was told the 04+ tb have no room for porting, but i couldnt speak from experience since i dont have the knowledge/skill/tools to do it

I think the best thing for the TB in 04-08 Grand Prix's is to keep it dam clean. Since it's electronic in nature it maybe best not to port it.
