Its a late 99 F250, 7.3, ive got the stock, 65dd, whisper mode, 65tow, 40tow, and 120 extreme. at least i think thats what they are dont have the order form right here with me so im not sure on the numbers. i have an DIY intake, straight pipe, Turbomaster adj wastegate controller, and the 6 pos. i dont know what codes they are but its in towing and dd when the truck boosts hard, havent tried it in the 120 mode yet. Truck hits 28-30psi, light comes on and power tops out. Really really annoying when you try to pass someone on the interstate. Love the chip otherwise, just curious about this.
