Re: 2588 vs 2388 extreme
We will burn a full tank of diesel in a 12 hour day, but we are also running a Hillco leveler which adds about 10,000 pounds to the total machine weight (thats the reason we turned it up). As far as how we know what the horsepower is, NO IDEA. The first time we turned it up it was done by our local dealership, and it was estimated, but when I went up with the screw driver I just guessed. We added a pyro and boost gauge to keep an eye on things. Our main issue has been on hot days when the air to air can't keep up. When its above 100 you have to back off the hydro, but if you keep an eye on it we have had no problems. Blow out your radiator every day, keep an eye on the exhaust, and go like heck.
We also wired the waste gate on our turbo closed so we build all the boost possible. Keep a close eye on the machine and you should have no problems.
