    So I bought a 99 f350 4x4 6 speed dually. I’ve had multiple 7.3s in the past. All were super strong. When I bought the truck it had a KC S300x turbo on it. Stock injectors and stock tune. It only made about 3 lbs boost at the time. I took that turbo off and put a stock turbo back on it. It now...

  7. 7.3L IDI Diesels (Not Powerstrokes) 1988-1993
    I posted yesterday about the truck (1988 7.3 IDI) not turning over. After hooking it to a charger it started but not happily, then it ran good and sat at 12 or 13 volts for awhile so I decided to take it on a bit of a test drive through town. Well, after hitting about the 3rd or 4th stop sign...

    240k Miles and no mods. Truck is having intermittent power surges, like I pressed the NOS button in fast and furious, while on the throttle cruising. It happens at idle too and revs close to 1k rpms and bucks when I let the brake off, the rpm is steady while doing this. The bucking happens...

    So my PS pump went the other day. While I have it apart to replace, i decided to do all of the hoses. I ordered all hoses from RA. However the 2 lines that arrived don't make it to the cooler? they are much shorter. I referenced the part i received versus what the interweb says :) and i don't...

    I can make it shift every time by revving up to 3000-3500 RPM and letting off the pedal. Had ABS codes and I got rid of them all by putting an OSS, Rear wheel speed sensor, and the right front wheel speed sensor, thinking it would also fix the shifting problem. No engine codes or ABS codes...
