JB diesel performance tuner????
 

Opinions please....

I was considering the RocketChip for mine. I know the engineers at RC come highly recommended in the VW crowd. I don't know anything about JB diesel.

+1. I am very interested in this, as well ad any other tuning options.

Fwiw, I contacted Dinan the other day, they said that they are developing software for the 35d, but do not have a timeframe.

Yeah, I heard that through the rumor mill as well. The only issues that I see with Dinan stuff is the larger than life price tag for a less performance oriented part than aftermarket. The only saving grace is the the warranty if you meet all their stipulations.

Jayjay, please keep me posted on how it works out. I am going to speak with Terry at JB tmrw and see what the deal is with these things. Looks almost too good. But we will see...

Great stuff IMHO.

I've got 24k miles on my X5, almost all of them with the JBD.

There are other options, but besides making a great product Terry and team are peerless when it comes to customer service.

P.S. - I recommend buying a BavTech cable along with the JBD. Cheap insurance. And if you like to work on cars you can bleed BMW ABS braking systems without a trip to the dealer or a panic stop ;)

JB is the way to go. Widely used on E90 (3-series) platform. Amazing power gain and customer service.

Very happy with mine so far! Just wish someone would work out the electronic throttle delay. That is incredibly annoying..

Throttle on a diesel? Where?
