Seems to be well respected in the tuning World. I'm probably buying a tune for my 07 LT with the 3.5 engine. Lyndon says his performance tune utilizing higher octane fuel, (plenty of 93 octane and even E85 in my area), is worth 15 to 17 horsepower at the wheels alone. Told him I'm adding a Cold Air Inductions CAI for his tune if it helps even more, he says it will.

So does a roughly 20 or better horsepower gain on a 07 LT with 3.5 sound like the real deal to y'all? Car is ALL stock other than these mods. Exhaust is stock too.... I've researched Westers heavily, he has a superb reputation. I'm not knocking the man at all, in fact I believe him. Maybe others on here might have had good or bad experiences?

Only downside is I have to send my PCM to him in Canada. I'll be without a car for 5 to 7 days. Says the 3.5 engine is a real headache to swap core PCM's out...this way I put my original back in, plug it up, and drive.

Thanks all,

Todd
