Hats off to Tuscany!
So the conversation started off with "Backpressure sensor? Really?.....lol
Now a little back story, I towed the car hauler 2200 miles to Darlington SC and back a couple weeks ago. On the return trip I noticed a very hollow sound from the motor and a little smoke on passing. It went away and there were no codes and I had no idea what caused it but I knew it wasn't right. I had told Bryan about it and he was at a loss as well. Fast forward to this morning and 60mph was greeted with the hollow sound again and 18psi just cruising on flat ground! WTF? Thos time it popped a code for a Back Pressure Sensor malfunction. What the hell is this? So I gave Bryan a call and he proceeds to tell me how this thing clogs up. Crap. So I pull it all apart and sure enough it's dirty and clogged. 20 minutes later it's back together all cleaned out and the truck is amazing. Now on flat ground at 60 I see boost between 3psi as a low and 5 psi as a high where before I saw 5 psi as the low and 8 psi as the high. The truck is much quieter and smoother and the power is much more linear. Thanks for the heads up Bryan, saved me a few bucks there!
