OS .15 CV-RX
Sorry, I guess it might have helped if I would have told you it was a TMAXX.
Just to let you know, I have since taken the truck out and continued to lean it very little at a time but still keeping it rich. I have ran approx. 8-9 tanks through it and it is even quicker and it isn't drinking as much gas. Fires up easy and accelerates very fast.
