Thank you. Theres a lot of good stuff there!

Would there be any tell tale signs that would suggest that?! Just sux doin all that work removing/installing pump. An now im not sure if the pump is warrantable any more. Work was done last summer. Would have to look at invoice to see

Ok thanks for the input. Makes sense. No im not running that setup anymore. Wanted to know if it was safe at all before trying again. An since the hp/mpg gains are so minimal its not worth it. Its just my daily driver/work truck. Thanks again Its just weird that i had that smarty lvl9 with comp 5x5 for so long with no issues on old pump!?

Was rebuilt at a very reputable shop. An yes they bench tested several times with no conclusive results. They reset the computer on vp44 an tested numerous times with no issues. The truck ran great with no issues before taking pump out on smary lvl9 an comp 5x5 setup. Only ran it that way cause i noticed that was the most fuel efficient combo for me. I guess im more curious for answers about if its too much timing for the pump an why it would cause the pump to fail. Dont even know how it failed after rebuild,the truck was working fine for a month or so...then one day after work i stopped by a buddies place for a bit. Truck was shutdown for an hour or so, then went to leave an it was really hard to start, took like 4-5 good cranks before it startd. Idled fine but as soon as touched throttle it would jump an pop like crazy!! Truck is fine now on smarty lvl8 an comp on 5x5. Just wondering if theres answers

I had my 2001 3500 with Edge comp box an Smarty S03 stack. Always had smarty on lvl9 an comp box on 5x5. Loved it! Truck loved it! Had to remove vp44 to do the tappet cover gasket an damaged the vp44 case installing it back in. Took the pump in to get it fixed an figured to get it rebuilt while its out. An now its tripped some timming code an killd my new vp44 on same settings i had for years before on old pump. Any ideas why this combo would do this to new/rebuilt vp44. The shop that rebuilt it fixed the pump again under warranty an had no answers for me why it would do that. Just scared to do that setup again an have to go thru all that work again pulling pump.
