Marco, I have a smarty (tnt) tuning on my 07 common rail. I recently had a Smarty Jr. On, then I took it off. I wanted the truck to be a little quicker now that I have built trans, intake and exhaust and I keep getting the P0191 rail pressure performance code. What can I do to resolve this issue?
Thanks, John.
