Ts Mp 8 & 6.7l Problems!!

[MMulrooney]

Installed a ts mp 8 in my 2007 cummins 6. 7 and it threw a check engine code for low rail pressure. Wondering if anyone out there has installed this and knows what I might have done wrong. It runs but has less power than stock. Any suggestions??

The 6. 7 ecm is looking at more info(and recording) than any previous models. I beleive that some of the software was written to stop the modding that goes on. One example is it not only records high rail pressure,but counts how many times and for what duration. The 6. 7 will go up to 27k stock,why would you want to add more?

I would stay away form anything that boosts rail pressure...
