sts twin turbo

[franc2]

Hi I have a 2010 300csrt8 with sts twin turbo with 20 gph progressive water methanol injection, boost is set to 8 lbs. the shop I have used installed the basic sts tune via the predator, as well further tuned using cmr soft wear. I have 2 problems that we can't seem to get remedied.

1. There is wot run on that occurs intermittently, more so after a pull from a dead stop.

2. During the pull from a dead stop there is a hesitation at 60 mph that last 1-2 seconds. I don't think it is transmission slip as the rpm says the same (5000) then goes again. The boost stays constant and the A/F stays the same.

Any suggestions... Thanks Brian

1. Its in the tune....

2. Not sure about that, but if you say rpm stays the same, and it stops pulling, it should be evident in a datalog as to what is happening there...

Thanks
