DPF Delete Pipe & ECU Reflash Source

^^I would love to go with Unobtanium but I do like that Alex can add in a top quality cat on the pipe in order to cut some of that diesel stinky down

That is something to consider. I had not confirmed the material. 409 could be an issue over time, that close to the turbo.

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

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?

^^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'm sure the parts will last 15+ years without an issue. But 409ss is prone to rust in high heat applications. I'm sure much of the factory exhaust is made of the same materials.

Yes you are correct
I copied that wrong

Thanks.
By the book, stock tq is 425. With my [estimated] 550 if I floor it under 1800 RPM and the [stupid] transmission doesnt downshift the torque converter damper springs will "chatter" almost scary I guess 20-30 ft/lbs more and something will go kaboom. We intentionally have took out some tq in the low-mid range so it is not extreme.
The rev limiter is set to 5100 RPM, but the [stupid] transmission will upshift before 5700 RPM. I am really eager to change the transmission behavior once the stuff discovered by Deftronix is up and running. If there is one thing that I hate in this car it is the transmission calibration.

I have no experience with aftermarket downpipes, but many guys here do. I had a flooded DPF that i gutted and installed, it obviously fits like original
To the California guys-has someone ever received a smog test notice? My car is in it's 5th year now and in the renewal that I just received smog test is not mentioned
