Does your mp8 change the tone of your motor any with twins on? My friend has one on his 05 and it will change the sound of the motor as you turn it up and down. On my 2003 with twins and tst it does not change the tone when you turn it up and down. Have not gotten to drive it yet. But it does start and run fine in the garage. Just wondering if it is working!

There might be something wrong with mine or it might be connected incorrectly (although I do not know how that would be possible with the plugs) because mine will do nothing until the **** gets right at 0% and then the engine runs ultra lean and stalls.

I have the same MP-8 on my 07 as I ran on the 03. It did not change the tone of the engine on either one. I ran a Van Aaken C3.2 on the 03 and that box made the truck sound different when it was turned on.. DWiggs, there was an extra plug on the MP-8 that you would use for different trucks. That one was supposed to be capped with a plug provided and there was also something else that had to be set to make it work properly on your truck. If you set that wrong then that's probably your problem.....Check your directions.....

Thanks Dodgezilla, I will.

Truck seems to run fine it is raining here today no way to get traction to see if it will work. Got on it at about 50 and tires came loose decided i will wait until it is dry out. With nobe turned counter clock ways is off i think. Directions i got don't say.

50% is as high as you want to turn it too. Most people see their best power on the dyno with the TST on 5/4. Yes all the way to the left is off. You should have gotten a little dial that is supposed to be mounted behind the dial...

jvjump

When i ordered it they said there was one in the box. But its not there i will call and see if they will send one.

Luken

I didn't get a dial either

I got a dial thing.....but i didn't install it. If any of yall can't get your hands on one, let me know you can have mine.

I never turn mine past 50%...and with the Hot Juice.....13.8 in the quarter on 34" nittos!

So how does it work today jvjump? And my truck is an '06. See you at work tomorrow.

Dodgezilla

The little dial is such a small flat piece that you guys probably just overlooked it in the box. If you still have the box it came in I'd bet it's in there upside down....

I will be on my way to fairview height in the morning. So i will have about 200 miles to find out. Did not drive it to work today. May be i will get some one to pick on me

Well the mp-8 works and it is very smooth on my truck. It is a great kill button when needed. I had a import behind me today with his radio shaking the windows and driving around like he was a road racer. So i rolled the **** to the right and let him have it sideways down the road. I dont run with the tst turned up to much unless im going to use it. Than on the highway a durasmack pulled up beside me and then went around slow!! So i turned the TST up on kill and the mp-8 about half way. Pulled up beside them gave a little puff. Then left him in a haze. I slowed back down they came around again and would not even look over at me. There windows were tinted and so are mine but i could see there heads staight forward. And to think they had a big old chrome set hanging off the spare tire. I will let everyone know what this has added to the truck as far as hp number when i can get back on david dunbars dyno! I want to thank everyone for there responses that helped me make this decision. It is nice to have all the info and spend the money once.
