G1625S

Well, I made my run out to Clarion, PA yesterday. I brought an 84 k5 blazer back. It was a little heavier than the Chrysler I took out, but not much. With the blazer, I weighed 15,200. Round trip was 615 miles. My honest-to-gosh hand calculated mileage was 18.3! I ran 60-ish on I-81 and close to 70 on I-80. The only thing I changed from my sig was I pulled a touch back on the timing and I disconnected my AFC. Couldn't use much pedal at all, but I pulled the long grades in 4th @ 63mph, around 2350 rpms, 22psi and the pyro hung in there at 725-750 (post). The mileage blows my mind, as I would have been thrilled with 12-13 I really learned where these engines are at home--it's just amazing how even a crusty old rig like mine can shine! I know 15k is not a ton of weight, but seeing how I have the lamest turbo ever and no I/C I was glad to be able to keep with traffic and not burn the old girl down. I've got a pic pending approval so everyone can see how shot my rear springs are Time for air bags

Excellent! That makes me want to hook something onto mine and drag it around.

The last long distance haul I did was up to Elmira, NY to pick up my brothers 96. Rough guess I was around 19,000 lbs. gross. Averaged 13 for the round trip at mostly 70+ mph.

I could pull any hill I hit on the way back in OD if I was doing at least 70 and I couldn't go WOT in 3rd due to excessive egt's at 30+ lbs. of boost. Kept the boost under 28lbs and I had no problems with egt's 1100 max at that foot setting.
