Cant Get Mpg or Boost Up?!?!?!?
Hi all! I've got the 7.3 in my sig, and the problem im having is that I can't seem to get my mileage to come up much at all.. it started out at about 10 mpg when I got it a few months ago.. and its slowly (very slowly) came up to about 12.5 to 13 mpg when I checked it last week.. I only have like 31-32 in tires, stock height, and i think i have 4:11 gears, but im not sure about that.. And I don't drive over 67-68 mph.. Im not sure what the problem could be??
I do have a tony wildman chip in it, and I think im on my highest setting but im not sure cause the tunes are not in the right order, but I didn't have time to send the chip back..
Also it seems that I can't get my boost to go over 20-21 psi? It seems like its spooling, ( you can sure here the turbo really loud) but it just doesn't seem like there's all the power that there should be.. I was pulling a car trailer with my camaro on it the other day and it was kinda having a hard time on our little rolling hills.. (more like big bumps. Ha!) I could only get like 10-12psi max, going 60-65 in 5th on any hills or even if I was just speeding back up.. I get a max of about 12 psi at 2000 rpm no matter what im pulling/not pulling..
I do think my back right tire is dragging alittle bit, but its not alot, anyone know how to loosen the brakes up a bit on these 350s?
Any ideas guys?
