Default Tuning 4.2L TB

Anyone know if EFILive is going to support the 4.2L TB ? I have a few people that want theirs tuned .
I have been to their site (EFILive) in the 4.2L LL8 P12 PCM section and nothing but people wanting tuning for them .

We've supported the P12 pcm for ~ a year now with great results.

We stopped our trade in's a while ago, but you could probably get a decent amount for your efilive if you still have a license or two left on it and depending if you have the older V1 or newer V2 version.

Yup

02-07 Trailblazer/Envoy 4.2 I6(we are the only software that supports 06-07 Inline 6 cylinders currently)

03-07 Trailblazer/Envoy 5.3/6.0 Gen3 & Gen4 motors/pcms(we are the only software that supports 07 Gen4 motors currently)

as well as many other models not supported by any other program.

No Hype, just a product that works
