I am still on a quest to eliminate the torque management on mt new TB. I have made numerous trips to the dealership to try and resolve my problem,but to no avail. It is operating as it should. I am just dissapointed with the "275 hp& 275 ft lb" it is "supposed" to have. Now I know that the engine has the potential, but GM strangles it back for drivetrain warranty reasons. I have gone to Westers web site,but they have nothing available yet,and when they do it will be a replacement ECM not a progammer. If I had a programmer, you could return the vehicle to stock settings if a warranty issue came up, but if I swap the ECM I can't do that . Westers wants you stock ECM as a core. Does any one know of any one making a power programmer for the '05 TB ???????????????
There are absolutely no handheld tuners available for the 4.2L engine. The Westers tune is about the only thing you are going to see until at least Christmas, and as of now they only have the 02 and 02 tunes done. Something about Gm changing the pcm mapping in 04+. I wish someone made one for the 4.2, but nothing as of yet.
