If you decide to sell that turbo then pm me. I've got a 92 idi and it does 3500rpm just fine don't be afraid to use the throttle when towing I have the E4OD and it shifts at 3200 if I'm on it.

 

I've had my 94 7.3 IDI for a little over a year now, and the temp guage has never worked. I just replaced the sensor and checked all of the fuses. I grounded out the wire and the guage moves. Is there anything else I could check before I take it to a repair shop? Thanks for any advise!
