Hello friends, haven't posted in a few months so here we go!! If your looking for little more power or MPG or even off road setups for your Cat, Cummins or Detroit let me know. If you have a spare ECM and want it setup for racing/pulling or just want a spare, send it in we can do whatever you want.

I do travel the northeast and could possible meet you if that works better. Can do just about all cat, cummins and detroit on the road, some more specialized off road stuff will need to be sent to me.

Shoot me a message and see if I can help your needs.

Steed speed c15/3406E one piece manifolds 1650.00 shipped. These have a lifetime warranty against cracking and can use factory studs, although arps are recommended for preventive maintenance. These produce much better flow than any manifold out there on the market. They will also allow you to run a larger ex.housing with same spool up of a small housing.

Been awhile folks, I have boost and fuel temp harnesses ready to go for cats with triangle boost sensor.

Also ready to tune up your Cat, Cummins or Detroit, from mild to wild I got you covered. I have a really good 6nz/2ws file for you guys who want a little more snap on the bottom end and it works great with the boost harness.

Shoot me a pm for info, can also do your ecm if you send it in.

Afternoon friends, anybody out there that has a 6nz or 2ws cat with a bigger turbo and looking for some more power? Do you not wanna pay the astronomical prices for a good power tune from the big guys (pdi,BD,PP,etc.)? Give us a shout, we have a great 650rwhp file (yes, the wheels). It is recommended to have atleast a stage 1 turbo with this file but can be turned down to run with a stocker at your own risk!!!

Please feel free to send a message for more info.

Howdy folks, anybody out there with a 6nz or 2ws cat looking for some more power let me know. I can help, if you have an upgraded turbo and manifold you can expect about 700hp. I can also tone it down if you dont.

Can't say I'm a fan of the Acert technology but they are probably the best platform to build from. If your not doing a full build I can tune your Acert to make great hill pulling power or even mildly tune it to improve drivability, let me know if I can help you out.
