Keep in mind the Buzzken is 409. One of the reasons I went with unobtainium.

Of course there is no way to know it exist because our websites are still non-functional, but if someone is interested feel free to contact me. Quite a few members here are happy with our tune and service.

P.S. I dont know what "Stage 2.5 Race" is, but our Stage2 is maxing out the stock fuel delivery system. With ~380hp/550tq the fuel pressure is dropping ~50 bar at high gear/high RPM, so that would be the limit for the stock fuel system. However all the hardware have proofed to be over-engineered, like in the old days. No ill effects on the engine or the transmission (even diff is still fine, filled with Motul synthetic fluid) after 17k hard driven miles, including towing car trailer, 21' boat and even 1 track day.
Looks like I have too much faith in my bimmers, perhaps this is why they dont usually break on me ;)

Thank you I updated my orignal post and I sent you a PM.

as for the stages i guess there is no FDA checking what stage 1 or stage 2.5 means but:

Stage 2.5 they(JR auto tunning) claim +85HP +135TQ from stock
looks like your TRF stage 2 is +120HP +90TQ
stock is 260hp 460tq

do you increase the rpm limiter as well? and are there any Dynos yet

^^Email Andrew - I don't think 409SS is an issue personally, but he is the fabricator and can answer any questions - [email protected] - he always responds to my email inquiries very quickly!

I thought the stock tq was only 425 in the US models.

What are your thoughts on the BuzzKen exhaust? I'll probably be going that round, and a HPEGR delete and your tune. I'm sure there's no surprises, but are you familiar enough with that hardware selection to provide the right tune on the first go-around?
