A friend om mine who has a power kit as well installed a JB+ to see how it goes. I didn't really know what to expect, but it feels great! Lot more punch from the bottom and around 4500rpm it really starts flying. It was set to 50% (on the standard JB+, not the special one you can get for cars which have a flash).

We drove with the Bav tech attached and no codes where thrown! Also the pressure looked good, did several WOT.

So what was your primary reason for getting the Performance Kit?

primary: cooling
second: power keeping waranty

it feels great. the car does not boost above 1.6 bar target ( regular JB+, settings at 50% ) which is more than fine where my 335i boosted well above 1.9 bar target. don't forget, the JB+ just changes the environment variables, every performance increase is done by the (OEM PK) ECU tune, with all safety checkpoints in place. No codes have been thrown ( except HPFP, not caused by JB+ ).

hope you get your HPFP replaced soon.

I am more inclined towards GIAC, honestly. I think I am going to go with GIAC stage 1 (or possibly Stage 2)...looks like a very good tune and I don't have a lot of warranty left. But JB+ may be a nice stopgap for the next few months...

Intake, FMIC, downpipes, GIAC stage II - go for it. Very different. We are talking about a very effective < US$300 mod here.

Looks like Eugene already missed his 335i
