I usually leave my Smarty on 9 and my MP-8 off or 30-40% around town and then turn it all the way up when I race. Works great with the Smarty

Where do you guys notice the most difference at and how much more will it smoke. It already looks like a train going through my small town! Also what else do I need to watch out for when i run it.

my truck smokes like a SOB when mp8 is at 40% or higher. It also smokes alot cuz of the turbo lag from the 66. WOT there is just a haze. If you run it at 100% you may have to keep an eye in the rail preasure make sure it is not to high. 100% should be ok for short times. I will run mine at 75 to 80% some times for long time and the rail preasure seems to stay in check. You can really feel it when you turn it up while holding a constant speed. You will like it alot.

Not trying to derail the thread but I thought the purpose of the modded CP3 was to raise the rail pressure. How do you keep it from going to high? Im a newbe.

Its more to increase the volume of fuel and move it at a quicker rate.

I found the best setting for me is 4.11 SW3, and MP-8 when needed...

I have tried the SW5, SW7 settings, but I got less low end response from them and the 7 had scary amounts of smoke... I think one of my issues is the Rokk sensor, and tone ring mod making to much timing...

Mp8 Finally on and man it runs awesome when I turn it on. It smokes super heavy now but only when it is on. Other then that the smoke is pretty thin even though I am runnin a 4.11 beta program. Awesome computer though and glad I purchased it!
