Call our shop, 315-299-4589, to discuss getting upgrading to the TS2ES code. They'll find out what rev you have now, if we need to have the control module sent in for modifications too, etc. and be able to give you the total price. To upgrade between V2 and V3 is one charge ($42), from TS2 to TS2ES is another $25. Both together may get some reduction, Neil or Ed at the shop will know. They'll also be able to tell you how long it will take to perform the work and when it should be sent back to you.
