Thanks Chuk, I'll try that. Actually reload the same tune I am running? Assuming you will reads this Chuk the muffler shop removed the brace that runs from the outboard side of the rocker panel where one would place a jack and then it fixes around the tunnel for the driveshaft/rear-end. They tossed the brace so it seems without ever asking about it when changing the muffler, it just made their work easier. I need to get a name and then a price so they can face the cost if they do not source one themselves. I wanted the muffler changed in like manner as the stock muffler so that brace stayed. I don't think the brace is critical as there is no different feel to the drive such as when a stabilizer link is left off. the owner who worked on my ride had a '71 Duster with a HEMI motor so I made that mistake of all mistakes and assumed he would treat my car as his, NOT!
Now I can get a few pulls and see what differences I see with the exhaust and this tune with 1.5* extra on top of the tune that was made for maxing the octane with TORCO. maybe I can find a shop with 100 near Punta Gorda/Port Charlotte. Sweet
