Tuning Quadzilla

Posted

Ok, so I finally got my truck back on the road after having to get another injection pump. Hopefully nothing else major goes wrong. At this point, I've replaced every major thing that could go wrong (minus the pcm and ecm). But I digress. 

 

My latest problem is whenever I drive the truck, if I don't have the tuner set on a higher level, it bucks, sputters, and blows white smoke. 

 

I'm 95% sure it's tuning related. I'm getting great fuel pressure and flow, and my injectors have all new tips (I rebuilt and pop tested them myself at school), and seals. 

 

I'm not sure if my specs are in my profile, but here they are again:

FASS 150gph pump, 1/2 line from pump to injection pump, Hamilton cam (so I was told,) 150hp injectors, and a 66/65/.84 turbo that has no wastegate, and dumps into a 5" exhaust all the way back. No muffler or anything. 

 

Long winded, I know. But where should I start on my quadzilla settings? 

 

If this is in the wrong place, feel free to move it. 

 

Thanks again for the help!

    Already got one on the way. I just wish I knew where the hell the old one flew off to. I remember pulling it out, watching it pop out of my fingers, and what I thought was dropping underneath the truc

    This is an indicator of slow VP timing, like really slow. Are you sure the pump key is in place, correctly, and or the right one?

    Always been fast even at +5° between bands, just looking for better efficiency. Been testing this for about 2 weeks now. By 3rd gear I can out right smoke the rear tires then bark the tires in 4th. Fu

It's a mechanical gauge hooked directly to the fuel line, and I have a damper hooked in before the gauge hookup. Would it help if I moved it somewhere else? I just bought it for a temporary solution. I'm going to order a glowshift gauge kit here soon and redo it all. 

 

Put a little needle valve instead of your dampener, then close it all the way and open it just a small crack just enough so the gauge rises slowly.

    Definitely I agree with that. The other looks better too. Autometer's aren't that impressive either. I have them and I want to go to ISSPRO's.

    Still love my EV2's... 

    I'm jelly, but shot my wad on emf ball joints and all new brakes. The EV2's are so nice though...one day, one day.

    Thats the word I was looking for, needle valve. I need to adjust it so the gauge isnt trying to fling the needle off every second lol. I do have one though before the gauge connection. I just sometimes don't know if the fuel pump is priming right, so I open it a tad bit more just to make sure it didn't close by chance. 

    I also believe 90% of my problems are from the bad battery on the passenger side, and the wrong key in the pump. But I got my biden bucks today, and ordered a beans micro sump, and a power distribution block to clean up the mess I have on the terminals. Once it's here I'm going to do the WT ground mod, and other ground mods.

     

    Thanks for all the help and info guys!
