Well, I have been running JB1 for over a year, and I really like the subtle gains I get with it. It also retains the stock feel of how the boost comes on. I have been thinking lately of possibly upgrading to the JB3 (pin-out), but I will probably wait until after warranty is over to do so. Have talked to another E92 guy around that has the V2, and he has nothing but good things to say about it. There are some others that have the SSTT, but have not heard their opinion on it.

At our altitude, the high boost piggy's will not have quite the hp/tq gains seen at lower altitudes because our little turbos will begin to run outside of their efficiency, so keep this in mind. Supporting mods such as Catless or High Flow Catted DPs and intakes will also help with the turbo efficiency, as well as a better intercooler.

Some of you Dinan Flash guys should chime in on this too, I am curious how you like the flash.
