I was not able to get a run of just the DPs without the intake this go around but previous testing with the intake showed around 7-8whp gains. So the rest is the combination of the DP and slightly more aggressive mapping allowable with the bolt on parts.

Very nice. This car feels like its going to respond well to better breathing. 400hp/400tq is nothing to sneeze at this early in the game. And you know Terry's going to start pumping out the updates soon.

Thought people might be interested to see my stock baseline on Blizzaks, 90 Octane and on a mustang dyno. This is to the wheel.

Ya they are hard at work on these.. Looking like a great engine. BMS has it on discount now for early adopters as well I think only for another couple weeks.

Impressive, so the 340i xdrive is putting out more then 400hp at the crank stock.

So your stock 340i on shitty 90 octane is putting down 338WHP on a Mustang dyno that is notorious for having low readings?!

Someone more experienced than me please chime in and explain how this is possible.

The BMS prelim Dyno also shows similar stock reading but on a dynojet, so the mustang dyno results are a little surprising. Might be a high reading mustang dyno.

Awesome ... the JB4 you sent me is working perfectly

Maybe my shitty 90 isn't so shitty. Haha!

Yeah, it was a bit surprising to me too.

Or it could be that it was...maybe 55 degrees in the shop.

No dyno yet?

This looks awesome! My 340i is on order and I'm really considering this.

Do we know if the MPE will add any power with this setup? I know the port installed MPE is a axle-back exhaust, but I'm thinking there will be some room to get more power.

Also - does a product like this void the warranty? If removed, will there be any trace of having a system like this installed?

Stock Exhausts on BMW are almost never restrictive. It might be too soon to know, but more than probably exhaust will be for sound not power.

Tune and DP offer most of the power gains on these cars.

Removing the tune before your dealership visit should keep you out of trouble

Good to know, thanks for the info! Do you know how long the early adopter pricing will be good for? I'm scheduled to pickup my car in mid-March.

Not sure how long it will last.
If you know you are going to tune your car for sure, there is no reason to wait until price goes up

This engine runs lean even with stock map

That's not BMS's decision. They can't alter fueling at this point. You need to alter AFR in the DME via flash.

Those AFR's are the stock values. Don't forget direct injection can run much leaner then conventional injection without detonation.

[Jeff@TopGearSolutions]

Would like to see it run a bit richer but since it's DI it should be in the safe zone.

Dont think it has been mentioned in this thread but the B58 JB4 is offered standard with the new enclosure
