Anyone switch from 1.5v to 1.45V

Procede comes with 1.5 version. Is 1.45 better?

Since the boatload of PROcede's Dustin shipped on Thursday were all loaded with v.1.45 (and Shiv has advised to roll back to v.1.45 on his forum), I would think that everyone has reverted back to v.1.45. I don't think I have seen a single person say "I love v.1.5!!!" yet...

Same here. I stuck with v.1.45 and will wait for 2.0 before making any changes.

Received the Procede with 1.5 but then switched to the '1.45 steptronic' version which I like better. Shiv made a special version for step cars.

I went from 1.5 to 1.45step and my car runs much smoother. Also lower engine temps and with 1.5 I had some BOV chatter that has not occurred since the change to 1.45 step.
