I've already got a more aggressive tune ready. More timing and a bit more fuel at wot. Just give us a call and ask Jolene to swap it out, mention what I said here about it. I'm not going to be very available for the phone this week --- 3 doctor's appointments and one with a new insurance agent so I'm playing catchup.
For Ken Payne: I have a Diablo chip, and from the seat of my pants, it has done nothing for my truck. '99 SD F-250, v-10, 5 spd, K&N, Granitelli mass air sensor, BBK 62mm throttle body, Borla headers, Flowmaster muffler. It seems as if I'm running on the lean side. It is the stock chip. Should I have ordered something different, or is there somthing I'm missing? Seems like others have experience some sort of gains from the product. Any info you have will be appreciated. Camo4stealth
The MAF, headers and tb cause a overly lean condition. The chip should have been custom programmed for it. There's a fee for custom programming. It requires that you fill out a custom sheet with your specs, fax it to us and then ship the chip. By the time the chip gets to us we usually have the code ready.
