I have got this code for the second time in about 3 months. Both times while driving solo, but both after a cross country trip bringing my stuff from Denver to here in Viriginia (towing 17-18K gross). I have a Turbo Master set at around 15# boost WOT, and all the mods in my signature. I am going to call Bill Heath next week to see what he thinks, but I thought I would get your opinions first.

I guess my question is why this code would come up with the Heath tune, and what I might need to do to not have it show again? Thanks for any ideas.

It could be boost is too high or too low. What is the boost guage reading when it sets?
