my spartan is acting up

[INHEAVEN]

Ever since my first go around with installing my spartan ive been a little gun shy with the turbo going out. I kept it on the 80 horse, then I upped it to the 120 for quite awhile. But lately I installed the 160 and I like the power, but I am very very worried when I pull a trailer of any sort.

This is now the 3rd time that my truck has completely shut down while driving down the highway. It has always been while having a trailer on the back and driving down the highway. When I get to a hill, I always take the cruise control off and drive myself due to this issue. When my truck has to gear down to 5th gear and the boost goes to what looks like almost 40 pounds, the truck will beep and then completely shut down, it did it to me twice while hauling the sled trailer on christmas break.

The first time it happened i almost hit the ditch due to no power steering but I managed to come to a stop. Turned the key off, turned it back on and started up and no lights were on so I drove away.

These last 2 times it happened during christmas break, I was climbing a hill and it shut down, so I popped it in neutral, shut the key off and back on and put it in drive, i could tell that the computer was confused and searching for the right gear to go in, but at the very least I didnt have to stop on the mountain side in the traffic.

I'm wondering if anyone else on here tows with the spartan on the 160 and has had these problems?

You honestly think you can have a 160 tune in and pull anything? Think about that to yourself... What's your EGTs?

sure, this wasn't what I was getting at.

Have you called sparten about this problem, obviously it should just be defuling and not shutting down completly....have you tried turning off all of your defuel settings?

I emailed mick at spartan and I managed to get a code, P0093. It reads fuel leak, large fuel leak. Mick said he knows of only one other person that had this issue and it started with the big tune and progressively got worse even on lower settings. So it could possibly be the hi or lo pressure fuel pump slowly giving out...
