DESERTTOYHAULER

Following up here. Had a shop pull an injector to look at the piston bowl.....its the 03-04 style, my truck is an 04.5.....been spraying fuel outside the bowl at the top of the piston the whole time. My suspicions were correct. The motor had been replaced previously......bitter sweet because I finally know why my truck smokes, but now wondering about the motor that was put in, hopfully it was a low mileage unit....the motor runs very well considering, looking forward to getting some Stage 0.5 BBI's with the correct pattern for the pistons.

"It could have a tone ring mod or rokktech timing advance sensor." I wasn't aware of the timing ring/sensor mod. I guess it was popular before the smarty software's were available? I'm not sure how I can tell if the sensor has been modified, but the ring will be obvious.

Switch between SW3 (towing) & SW5 default with 75% POD. I switched to SW4 this morning to see if it smoked less w/o timing, but no change. It smoked/hazed bad before I added the smarty.

If someone possibly swapped and early 04 long block into an 04.5 truck with 124* tips, how would it perform? I'm asking because I'm running out of ideas on why my truck hazes and smokes so bad.
