1st question: I need a customer tune please, i installed the egr delete plate and its throwing a code p401. I use the 85 tune

2nd question: Is updating the best thing to do in general? If yes then I would prefer the custom tune to be set for the latest revision on the u1786.[/u]

a customer tune cant be made for off road use??

You could always get what's called a fingerstick. This fools the computer and that code will not come on again.

thats the best option...
