Sooo still haven't had a chance to dyno the car.. but I have been bored lately and did some more searching for tuning. Nothing comes up BUT.. racechip. I have heard a few ok things about it, read someone who did dyno his car and had NO improvement (but racechip did work with him). Now what's really funny is that racechip.com (Europe) does have the m35i listed.. +31hp, +50nm torque. RacechipUSA does NOT have it listed.. however they list the 28i as +63hp +70lbft which is similar, if not higher than X1/b48 tunes. I sent racechip an email to ask why. If it's $500 for the GTS black, I'm unsure if it would be worth the +31hp +50 torque.. but it would show that there's a lot less wiggle room (I'm thinking boost mostly) to squeeze more out of it.

Interesting.. The unit itself looks very much like the racechip module along with the number of features.. Price wise another big jump! I do not know much about DTE systems.. have you any knowledge?

I'm thinking of trying the jb4 since I can log and tweak. It's still a piggyback so it should behave nice with the ECU and warranty.

I got an email back from Terry @bms and he said it would run.. Just send the logs and then he can look at it to see how much we can tweak it.

I’m just ready for Bootmod3 to unlock it and give it a go.

The only issue I have (other than they haven't even mentioned trying to unlock it) is that with a flash I'm pretty sure it's detectable and if ever a warranty issue came up that would be suspect..vs any piggyback should not be..

Think I might try this DTE thing, and bundle with the Pedal Box.
