Default Just Installed My Re-Programmed PCM

First of all. Huge kudos to the speed of PCMforLess for the turn around of the loaner & re programming mine. I received the loaner last saturday morning, took mine out, installed theirs, went to the post office saturday afternoon, and priority mailed it out. It came back last night, tuesday night re programmed. How an earth that happened so fast is beyond me.
Now the fun stuff. Installed the re programmed PCM, and the truck fired straight up. I have Toyo 35", and a K&N air filter.
The difference is VERY noticable. More pull, more all around power, better shift points, and also firmer shift points. I have to go through some mountains on my way to work, which is 30 miles one way. I generally went into 3rd up the hilly parts so as not to lolligag. NOW, it does it in D easily and better than when I went into 3rd before. Drop it into 3rd, and YEAH BABY, this is what I have been looking for. This is a very impressive addition to this truck, and has made it a joy to drive. All the positive comments that have been published on this forum about PCMforLess, in my opinion, are right on the nose with there comments. In fact, I am so impressed, I am going to do my wifes Z71 tahoe.

yes, I am running the 87 octane fuel. I am also going to go 4 wheeling friday(any AZ wheelers want to come. Mud Springs, Log Corral & fr393). I am really looking forward to see the low end difference for wheeling.

It takes about a tank of gas to get the full benefit of the programming. To help the idle relearn, start up the H3 when cold and let it warm up to normal temps.

OK I just got mine yesterday (loaner). Now how hard was it for you to get the damn plugs off. And did you move your washer fluid bottle and over-flow?

No need to remove anything. The 3 plugs might be in there pretty good from not having been disturbed from the factory. Pull up on the red tags, lift the lock ALL the way up, and carefully wiggle the connectors off. it might take a few minutes, but they will come. I sprayed the connectors once they were off with electronics cleaner. Ensure on install that the plugs go all the way in.
Follow the instructions on the loaner for re learn. its all very easy.
