LS1 or LS2??

[Mike Norris]

When it comes to the TB, there is compatibility issues when mixing different ECM's, TCM's, TB's and sensors. I always am sure to use a matching ECM/PCM, TB, MAF and other sensors.

I reference this after having a 69 CamaroI tuned with an LS2 the customer installed out of a GTO and ran great. He then installed a Magnacharger and TB out of a 2006 Trailblazer SS. It would not run well at all, backfired on accel and kept having throttle position issues. Put on a GTO TB and it was perfect.

The reason he put on the TBSS throttle body was the GTO TB had mounting issues with the TBSS Maggie setup.

It may cost you to get a complete GTO PCM, harness, TB and sensor setup and ditch the TBSS stuff, but actually save $$ and be less headaches in the long run.

Hope this helps.

Glad this was confirmed. I did find a good deal on a TBSS throttle body and I jumped on the LS2. Do you know if a 2006 Impala gas pedal will work??

I am not sure on that compatibility for sure. But as with my other info in the previous post, I would use the proper DBW pedal that matches the PCM use. Just another potential caveat when mixing parts from different applications.
