[QUOTE="CurtisF, post: 311633, member: 829"] Really it's been a long road, and I had a ton of help along the way. But yes it's about getting PW, ICP, and timing right at certain points. Problems I have encountered included too much ICP and too little fuel, causing a truck that ran rough, ran choppy at certain RPM's, and just didn't have good street manners. Then there's the other side where I had issues over fueling, and blowing out too much smoke. It's a balancing act. Actually, what's funny is the tune that I did the emissions test on runs and drives almost exactly like a stock tune. I pulled fuel out from my normal daily driver, and did a few extremely minor tweaks, and the result was a very mild mannered, easy stock-like tune. It wasn't too sharp or crisp, and was actually very quiet with a good linear response on the pedal. [/QUOTE]
