I got in my PCMFORLESS tune today and put it in an hour or so ago. I really didn't know what to expect, but either way I am pretty happy. The truck didn't run all that great on even the relatively mild early LS6 cam with the stock tune, but boy it does well now!

I was going 40 on the highway and decided to punch it an instantly it threw back and shot off. I was watching the revs and it was @ 5K something but I was hitting 90+, and got scared of cops so I backed off. (I was running on the 3 mile strip of road between the county jail and the police station ).

I've only driven it about 7 or so miles so I can't really say much more about it as far as performance results (which are great so far), but I do know it just drives MUCH better. It feels like it has much more torque than on the LS6 cam with stock tuning. I'ld say that now it feels kinda "stock plus" on the low end, mainly b/c of the tranny settings, and "stock plus plus plus" on the top.

He got it back to me very quickly, and did a pretty good job. I do have an SES light that is probobly still from my cats being off (though I did ask for that to be tuned out) but it could be something else/ normal. I'm not sure.

I really have no basis for comparison other than the stock tune, but I can say that for $250.... well, I'ld say its a good cost effective mod.

 

awesome that your ride is running better now.

 

Yeah, I'm pretty happy about it. When it was running really bad I was ready to sell the truck or at least stop modding it..... Now I'm thinking limited slip in a couple of checks here. I just gotta figure out how to install one.
