Shifting: After having my tune for about 6 months or so... I WOULD NOT go back to stock. I got the shift firmness 2 and I am nothing but happy with it. Shift's Just like a tranny should. The hesitation with the stock tune is annoying and very unpleasent. The tune took my shift points and tweaked them a little, and the shift firmed up with a quick (Compared to stock) short shift. This isn't "stiff" as some would call it nor is it "soft". I haven't tried level 3 but I would like to.

MPG's: This was made me order the tune in the end. I was expecting maybe 1 or 2 mpg, and Thats about what I got. I have 115,000 miles and I drive about 500 miles to my cottage (Round trip) about 20 times a year. Mostly city other than that. I got a solid 22mpg which is Very good for my vechical. I also noticed about a 1 to 2 mpg city. I am getting about 13mpg to 14mpg city.... Which I am lifted 2.5in. (No Tires Yet) and Do not drive lightly. To me this has saved me hundreds in trips to my cottage. All I have is good things to say about Pcmforless. I had no issues with the tune.

If you have any questions about the tune please let me know. Also, It gives the truck a sporty feel!:yes:
Thanks,
Trent

I'm seriously looking at this option myself. The shifts are too soft and throttle response is lacking.

Could you reply with the other options you picked in your tune, octane, rev limiter, gear skip, towing, etc? Did you keep your old PCM or send it in for the tune to avoid the CASE and security re-learn processes?

Thanks
Tom.

I went with standard 87 octane. Which going to 93 would have small gains. I took off the rev limiter. Gear skip?? Whats that? I said I tow frequently approximately 2,000 pounds or so. And I sent in my trucks com while I wasn't using it. Everything else I left to them to pick. I also tuned it for a CAI. I wish I got it tuned for a cat back though...

I stayed with 87 octane, firmness 2 and occasional light towing, tuners choice for a lot of options since the Voy is stock under the hood and in the drive train. I forget if I had to tell them the rear ratio.

Will I willingly go back to a stock PCM? NO!!! The Voy is really fun to drive now.

I pulled and sent them my PCM as I had another vehicle that I could drive and I had it back in about a week.

Sounds great. Which CAI did you go with? I was thinking of making my own from the stock box eventually. On the PCM site there was an option for skipping gears if so enabled, don't think TB's run that but I'd want it turned off if it did. Not planning on any other mods except for adding/swapping a limited-slip in the rear diff.

Stock air intake. Until I found the other site and then here I hadn't made any mods to the Voy other than a Scan Gauge and my amateur radio transmitter. The tune is the only real performance mod I've done.

The PCM tune has been on my list for a long time, decided to wait till the extended warranty was done, good thing I waited because I blew the motor, I'm sure GM would have blamed the non factory tune for the engine failure. Now with the new engine my 3 year warranty expires in March 2013. Only 3 months away now :wootwoot:, I think I'll have 80% of TM removed since I sometimes tow a trailer.

I have PCM tune in our 07 IL6. I like it. Been awhile, I think I ordered tune 2?, don't remember without looking it up. Anyway, wife could care less but I like it. Performs as advertized AFAIC. I used the loaner program. Worked flawlessly. Just followed their instructions. Been there so long I don't even know it's there. Prolly increased the mileage a little. I got it for the improved trans operation and throttle response.
