[Devon Harley]

I have and 5sp 89 7.3 4 in straight dump ext. 2 flat ip delphi inj. and i installed a boost gauge today runnin 9 psi whats the normal 15 is max hows that though can i sqeeze anymore out?

Are you saying your max is 9?

If so,


if you arent smoking like crazy and your exhaust temps arent to high then you could try to go up with the fuel some more but if those are unloaded numbers then I would think you are doing pretty good for a nonwastegated turbo.

If your max is 15 I wouldnt try to squeeze more out of it

15 about the max i have hit empty. know there is more there if turn the pump up more but wouldn't do it unless you got head studs and inner cooler

Also hows that 8in tip jus wondering im doin a 5in tip?

9 lbs without a load on out of an 088 is nothing to sneez at... especially when you consider that when ATS built the kit, they figured it would run at peak effeciency at 7

800 deg unloaded could make it a pain to pull with if you increase the fuel much more, the 8 in tip is ridiculous but I got it and all the pipe to go from the carrier bearing, over the axle, and exit out the back for 40 bucks. I cant tell you what kind off difference the tip made because I changed the whole exhaust when I did the tip. Honestly if you dont have a big lifted truck 8 inch looks way oversized. If I hadnt have gotten such a good deal on the big tip I would have went with 5 or 6 inch.
