I am looking at the livewire at mpt tuned by morepowermike it says. It's new not used get 3 custom tunes and 3 pre programmed. How bad was it to get in there to drill and tap for the probe? And easier ways than others?

 

I would stick with one of the more well known tuners. I've never heard of MPT, or morepowermike.

I would use:

Eric @ Innovative Diesel
Matt @ Gearhead
Doug @ GoGo
Vivian @ Quicktrick

It was quite easy, just slide under the truck you have plenty of room, didn't have to move anything. If you go to www.dieselmanor.com you can see pictures and instructions on how to install gauges on almost any diesel pickup.

 

Ok. Thanks for all of your help! I'll let you know how it all turns out
