PCM Tune
Hey everyone,
I have searched the forum and some other online searches about PCM tunes for the H3 3.7L. Anyways I have a mechanically stock H3. I have 35 nitto mud grapplers and front end leveled. Obviously since the increase in tire size I have noticed a big decrease in gas mileage which isn't a huge issue because hell we all drive trucks and they're meant for off road and terrible gas mileage. What I would like to improve on is the points at where the trans shifts. I know that everyone else on here has the pcm tune and I would like to know a little more info on what exactly this means. Do I need to buy a new one or can mine be tuned at a local shop. Also what is the average price for one. One other modification is a intake resonator delete to just a straight pipe.
Thanks in advance for any help.

Also here are some pictures of my intake setup.
This is my setup for right now, the next step is to send that tube to the left and send it over to the fake air cap, it already has holes in it and works just fine.

Thanks a lot for the help. It's definately something that I'm going to look into to hopefully get the HP back up to where it was before the tires. Well at least the same feel. Lol. Have you noticed a difference with yours?

I have found that you sill still lack some power. I would do a cat-back, intake, ported throttle body before doing the tune. I love PCM4less tune. I run 35's on mine and the tune and ported throttle body are the best mods for power, at least by the seat of the pants.
