What are your overall objectives with your truck GRI? are you building a street/strip beast? or a tow rig?

 

mostly a tow/daily driver. but I like leaving ricers in "the cloud"

right now if I put my race box on 140hp (L3) from L2 (100hp) I wouldnt notice it. not really.
If I put the extreme (160) tune with my diablo it is night and day from performance (100hp) low and top end


if I could gain 40 hp right off the start I would be more than happy

 

I think I know what your problem is... besides the addiction part your running out of fuel... your pumps cant keep up with the boxes you've put on there. the higher the settings the worse it is. I currently have a fuel filter with about 13~14k on it and it's time to change it (today)... on my TST I have the rail pressure gauge I can look at while driving and I see that on the higher settings, the pressure is dropping from lack of fuel. I'll bet in my case once I change the filter and have full flow again, the pressure wont drop. If you bump up your power so much that the pumps cant keep up, you'd have the same issue with the rail pressure dropping.

your next mod needs to be a FASS or a Walbro pump... once you have that installed, you should have no problems leaving wet spots on your seat

 

I was thinking that could be a possibility. I will know when I hook the commander and pressure kit up to the truck

 

You crack me up !!!

One month you go from one exhaust system to the next and wind up installing 5 + exhaust systems, and now you're doing the same thing with chips.

 

oh stop this is the second set up I have had. Im just adding to to it. maybe. lol

 

this week end Im going to do a test and compare each one of these. and see if my diablo or the quad is better.
I have a feeling that the quad is going to have better fuel mileage.
