03-04 TrailBlazer/Envoy 5.3L LS1B Tune Request

[ScarabEpic22]

Hi all, does anyone have an 03-04 TrailBlazer or Envoy 5.3L LS1B 1MB PCM tune? I have tons of the 4.2L I6 P10 files but I havent come across an 03-04 5.3L tune yet.

Thanks,
Erik

Nope me either, haven't seen one yet, plenty of the LL8 as you said, maybe Paul or Ross has one.
I guess the EXT are soccer Mom rides.
Would think they are real close to any other 5.3L though.

Thats fine, I just need the TB OS because the PCMs are a dime-a-dozen! Cant find the OS anywhere and I dont have access to Tis2Web.

How about a 2006 saab 97-x?It is just a fancy trailblazer really. It has the 5.3 LH6 all aluminum engine. I am just wondering if it uses the same ecm as a trailblazer?? I have one coming in thursday morning for a bad oil pressure sending unit I presume. Should I attempt to read it??

Please do, it'll be an E40/T42. :D

I still need the 03-04 5.3L because they use the LS1B PCM.

Ok I will check it out and try to read it. I drove it briefly yesterday as the owner had a vibration complaint as well as the oil gauge not working.It is a pretty quick suv. I have had 2 or 3 4.2 in the trailblazers come in, like you said a dime a dozen. Stay tuned.
