Just installed DAP 7x10 sac injectors yesterday in the 2001 24v. I set the quad to 150 fueling by 18psi but am only hitting 3k to 3200 max fueling. Is this normal? Should I be maxing fuel? I don't feel any power difference after installing the injectors up from stock. I'm hitting 30-34 psi on the HX35 just like before. Not really anymore smoke then stock. I started the fuel @ 95 @ 0 psi and ramped it up to 150 by 18psi and figured it would hit 4095 but it doesn't.

I’m sure if he babies it he’ll be fine for a while, just really hard to baby it when you got the go fast parts on!

Your tune is starting way to low for those injectors.  I might ask DAP to go over the injectors again.  I know @dodgeih was fighting similar issues and the injectors, not dap in this case, where to blame. It could be that something is up with your set.  It happens.

 

The gearing doesn't help but you should be able to tune it smoke free, it would be a pig, but it would be smoke free.

Im trying all kinds of stuff with the fuel. I brought it back up to 86 going up hitting 116 by 30psi. Seems to not smoke much anymore. It wouldn't start this morning @ 75 @ 0psi. I don't mind playing with it and changing things around. That's why I bought the quad, I like to fool with tuning. How do I turn off pump tap in the settings. Just drive on level 3?

Keep in mind the the quadzilla is effectively off during cranking, so it wouldn't start in the morning it is related to some fueling issue.  

 

To disable pump tap just run on lvl 3.

May have been from not running the grid heater then. I figured 50 degrees out I could skip it and just crank. It would cough quick and stall. 

I'm having similar problems. I think I'm losing prime. I'm going through the fuel system from start to finish either this weekend or next. It gets worse the longer the truck sits without running.

I'm without grid heaters right now and able to start down to 30F easy. I'd say fuel system issue or air leak.

Seems to be ok. The wait light goes off pretty quick and it fires off. Just that one morning I didn't wait and it would just burp quick and stall. Did it about 3-4 times then started. haven't had a problem before or since. Weird.
