It's funny, because I'm not big on smoke either. We have worked very hard over the years to make files that run clean and strong. At one point in time, we did make files like Smoke Show and Lope Idle, but we've long since done away with those. In fact, we've taken heat from customers that wanted us to build those types of tunes and we've refused.

In your situation, we can certainly tone down the low boost fueling to eliminate that puff of smoke when laying into the throttle, but the downside would be a bit of turbo lag. It really comes down to the idea that those trucks need all the help they can get to start moving, so the compromise was to add a little more fuel in the low boost area to help get moving and get the turbo spooling. Of course, that was on the big file, so dropping down to level 4 or 5 would also help clean the exhaust up.

I'm certainly interested in hearing your thoughts on the drivability vs. smoke. Whenever you have some time, feel free to give us a shout and we can discuss it. Or, if it's easier, we can just plod on through here. At least then, other folks could benefit from the conversation.

Keep me posted.
