I hope I'm that customer!! Because it works GREAT now!!! I'm not into smoking people out or anything like that either, but I live in the country, and I'll admit, I love to roll into it on a winding back straight-away and see a little smoke.
The tune that I recieved is actually as smokey or not as you want. Stock injectors on work one way, and the truck SHOULD spool the turbo

.
So you're not going to get a HUGE amount of smoke when you punch it from a roll, but you can get a good bit if you know how it all works. Mostly, I like rolling into it in 4th with the TC locked going down the road. This new tune will smoke, and smoke, and smoke, and smoke, if you roll into it just right, but eventually your speed/boost will increase until it doesn't smoke much, but I don't recommend that, due to EGT's maybe getting out of hand.
Anyway, what I'm saying is... Smoke is bad in the wrong place, at the wrong time... VERY bad. Whenever I see a guy blowing smoke in town, or acting dumb in front of the wrong people, I get mad, but smoke at the track, or in a secluded area is OK if that's what you're in to.
The lope tune works great as well, really gives it that cool sound!
Disclaimer: I didn't buy a smoke tune, my little brother did, but I stole his chip for the week.
