Hey guys im new to this site and new to diesels. Me n my dad are chevy mechanics but never really messed with diesels until i bought one. i recently in the past 15 days bought a 2004 2500hd ext cab short bed with 218k on it. it came with an intake and a powerplay mp-8 chip? have no idea what this is for an why its there i looked it up an found its for gas but messes up truck when i turn it all the way up. any ideas? any recommendations for upgrades.

Power play

here is the info I found on power play, dont know personally I have only ever seen one other person that had one, anyways

The TS MP8 is a universal performance module that holds eight brand specific programs. It contains all diesel brand applications on one chip board. It is the only universal module on the market and the only one that is always upgradeable and never outdated!

The MP8 holds eight programs and when the appropriate harness is connected it will access the programs for the application and it will marry the harness to the MP8. This module is also stackable with many other performance downloaders and programmers. The MP8 also has an incab adjustable knob so you can control the amount of horsepower you desire.

Since the MP8 will hold eight programs you will always have an upgradable module even if you change brands of trucks. You can send it to TS Performance and we will reset the MP8 and you can just purchase a new harness for your new truck. This will elimate the problems of having to try and trade or sell your old module. This is also an option no other manufacture can offer the end user.


hope that helps

what do you mean by it messing the truck up when you turn it all the way up? what does the truck do?

 

[20chevy04]

It sounds like a shitty lobe idle it just about shuts the truck off and then it comes back and does it again and i have no throttle response and if its all the way up when I start my truck I have no pedal response unless I push the pedal to the floor then I only get 2k rpm

Sounds like it is in limp mode. Check engine light on?

 

[20chevy04]

Nope no lights on my dad said it sound like the engine is about done because there's a smell of diesel fuel an I my throttle respond sucks now like it clogged or something I've only had it a week an had so many problems

Have you tried removing (un-plugging the MP8) and just running it totally stock?

You may have a bad module or corroded connection.

Take it out of the equation and see if the truck runs like it is supposed to....

i would check your fuel filter too! im sure you have thought of it but its often overlooked

 

[Burn Down]

^^^ X2 on the fuel filter & removing the mp8. I would change all the fluids and filters on the whole truck, so I knew what I was working with.

 

[20chevy04]

will do ,an let yall know thanks

 

[20chevy04]

to remove it what do i do? just follow it an unplug it then plug stock back it where i unplugged that?

 

[Burn Down]

I would think so, never been around one.

 

[20chevy04]

i took it out and it is running better but idk because ive never driven a completly stock diesel so idk about the throttle response but the truck sounds better and i found a black wire that came out of a connector end will post a pic in a min.

I had one in my truck a long time ago it plugs into the rail pressure sensor and the map sensor. When I bought it. It was to help control rail pressure. I know when I had my ppe set on 5 and the ts up it would limp everytine. Never had your problem tho

 

[Chevy1925]

there will be a little lag off the start if you do a full throttle run from a stop and so on in traffic. the biggest thing you will notice is when your comin to a intersection and get that yellow light and you hit the throttle to go through it, by the time you get through the intersection the truck will have finally down shifted, got ontop of turbo and started pulling hard lol. took me a while to figure out i cant do that anymore when i first got my truck 5 years ago

leave it off. its not gunna help you much. your better off with a ppe programmer, ats programmer or get efi live

 

[20chevy04]

ok thank you and also which other upgrades should i do ? would a bigger waste gate do much or just a programmer? i was looking into the ppe hot+2
