Here we go...
Im going to change my plugs tomorrow. Im also going to pull the pass. side exhaust manifold to remove a broken stud and change all the studs. Should be a good time. Ive got 98000 on mine and last year I had a plug come loose on me. I found it and retorqued it, checked the rest and have had no problems since. Let you know how it turns out.

all done.
Well, did it. It was actually easier than I thought. I work on heavy equipment and this was a walk in the park compared to other things if you have all the right tools! Broke 2 more studs pulling the manifold but nothing an angle drill and some lefty bits couldnt pull out. The gap on the plugs I had pulled out was about .070. Truck still ran great. Seems like it runs a little smoother, but it could just be all in my head.

When I get a chance I need to replace the studs on my truck. Glad to hear all went well.

After several miles of driving with my mods so far (General maintenance and SCT X3 from 5 Star). I am up to about 11-12mpg in town(up from about 9) and 14-15mpg on the highway(up from about 13).
Last weekend we went on a good ride where I put 200 miles on my truck round trip pulling a 16 ft trailer and my rhino (combo about 3000lbs). Going to the ride I was on all back roads that were slow and curvy (averaging about 40-45mph) spending a lot of time in drive with overdrive locked out and I average 12mpg.

Last time I filled up I decided to try 93 (even though I am using the 5star 87 tune) Today I filled up today with 260 miles on the tank and averaged by hand calculations 12.5mpg with some idling some town driving and some back wood highway driving...
I filled up till it clicked off a couple times to get to the nearest dollar with 93 again..... I drove (casually) another 82 miles after fill up of good highway driving and very little in town, I decided to fill up again on the way home and at 4 gallon it clicked off and several clicks later I finally got 5 gallon in it which would equal 16+mpg (4 would have equaled 20mpg)........ I know at 82 miles it is hard to say but I think next fill up I will try the 93 again and see how it does.....
