    They need to lower the mph and rpm shift points for each gear. Take it back and try again... What are they tuning with ? HP Tuners ?

    Set at 5600 with a shift poing of 6300. This is just me but it sounds like the tranny is starting to go. I would double check with Frost. When your shift points were set higher I would not have said that. I would have backed down or gone back to stock shift points to see.

    I ran my stock bottom end with the same set up, until it pulled a rod bolt.

    He has to lower the mph shift points too. They can be zeroed but I didn't.

    I had my stock bottom motor hitting 10.8's with a 150 dry shot. Walbro 255 fuel pump & 30lb injectors at the time. And a little more tuning ! LOL
