Great results from PCM for Less tuning . . .

I have put 1,600 miles on my H3 since the PCMforless upgrade. I have 315/75-16 BFG MTs with 35psi all around. Average highway mileage is 15.6mpg and back and forth in town is 14mpg. I drive back and forth from Morristown, NJ to Providence RI regularly so have gone through many tanks of gas and my mileage has been pretty consistent after the first tank.

I put in my reprogramed PCM Tuesday. Tonight I put in fuel. After 187 miles, I was able to squeeze in 9.6 gallons. You do the math.
Most of this winter I was running between 17.5 and 18.5.

My opinion; Truck runs easier on the highway. Takes off better and shifts cleaner. I'm happy I did it.

I took a trip over to Helena from Great Falls. Just to put my drive in perspective Great Falls is over 3,300 ft in elevation and Helena is just over 4,000 ft. To get to Helena you have to cross the mountains, so I would say I was climbing some grades that ended up being 4,500 -5,000 ft. The shifting was great going through the mountains on the interstate.

On the way over I was getting alot of head wind also, the wind was probably at least 40 mph coming head on. Had that wonderful flapping with the marker lights. The wind is blowing 30 mph outside now.

I did 173 miles and got 14 mpg with the 315 tires. I have a little over 312 miles on the pcm now.

Westhillsat - got some more feedback, now that you've put a few miles on with the mod?

Not much else new, other than I have to watch the foot on the gas.
Very smooth and if I don't watch the dashboard I'm over the speed limit in no time.

I took off my marker lights today and put alot of 3M automotive tape on the base of the lights, I'm just going to keep the truck in the garage this weekend and give the adhesive time to set.

The trip to Moab via Denver will be the big test.

When we go to Moab I'll take the radar detector along. Seriously, prior to adding the dual exhaust and having the pcm done for me it would have been kind of silly to have the detector in the truck.

Now it is like a totally different truck for me.

Hey West I went to Napa and bought a tube of black window sealent. It was about 14 bucks, but it worked! Finally! I recommend it to anyone with the a-pillar problem. I did it abou ta month ago and didn't want to say anything until I was sure it worked. I hit 90 today in a headwind with no noise.

Just wondering has anyone with a manual trans, tryed a upgraded pcm?

If I have anymore noise I'll try that

Mind sharing what you had it set for?

[deserth3]

No problem.
Stock 06 with adventur package.
Sock tires. 285/75R16
I picked 2 for the shift points, towing above 1500 lbs, high altitude, regular fuel.

I do mostly highway driving, and live just over 4000 ft.

Thanks
