I would love to upgrade my sway bars, but the installation looks like a pain in the rear.

Or in the "front" depending on which bar you're installing

I was actually very excited to see this company step into the b58 game. Some of their products really caught my attention, mainly engine and transmission mounts. So when my coming up last month and my girlfriend asked me what I would like I immediately thought of 034 transmission mount since the engine already has power flex engine mount inserts. A week before my bday she ordered them with 2 days shipping (listed as in stock). We are going on almost 3 weeks with no shipping info sent and couple days without a reply to the email asking what was going on with the mounts. I understand parts delays as I work in the automotive industry but nothing leaves a bad taste in a customer's mouth like taking their money and leaving them in the dark. I will not be purchasing part from this company again or will recommend them. At this point I do not care about the mounts just upset that my girlfriend is down about the situation. I've advised here to cancel the order pursue a refund.

----------Im sorry if this is not where this goes. Ive never posted before----------

I have a 2018 BMW 340i GT XDrive. Upgrades are listed below and everything else is stock. I have easy access to high quality 93 octane gas with 10% ethanol or less in it. As well as easy access to E-85 gas with a rating between 51% - 83% Ethanol. (Cleveland Ohio area).

• BMS B58 BILLET INTAKE
• CTS TURBO 400 CELL CATTED DOWNPIPE
• BOOTMOD3 - STAGE 2 ENGINE TUNE
• XHP - STAGE 3 TRANSMISSION TUNE

On Stage 2 /93 Tune, with 93 gas the car runs GREAT. I ran ¼ mile in 11.8 and beat a 2023 C8 stock vet at the track. In this setting the Sport Display shows a max HP of 560. I am topping out around 510 hp. All the math I have done from my track times, and my weight says that I should be somewhere around 505 to 520 HP which lines up with everything else.

On Stage 2 /E30 Tune, with E30 blend gas by mixing 93 and E-85, the car runs good…UNTIL, I give it full throttle. Then car loses all power until I release the throttle a bit, then it backfires and then takes off. This same occurrence happens from a stop and from a rolling 20, 40, 60, and 80 start. Also the Sport Display in the E30 Tune, only shows a max HP of 480.

What I’m curious about…

•Everything I have read says that the E30 Tune should be faster than the
93 Tune. If this is the case, why would the Sport Display show as 93 at
560 HP and E30 at 480 HP?

•Is my issue with the E30 something to do with my stock fuel pump not
keeping up?

I would like to know what I can do to get my ¼ mile time to low 11’s, and is an E-blend the answer?

** This is also my daily driver, so I am not looking to do anything crazy that will significantly reduce the life of the car.

Wrong place to post this, but i'll give you my thoughts anyway...

Likely your fuel pressure is crashing running too much E on the stock pump. You should either stick to the 93 tune with your stock pump, or upgrade to a TU pump and run the e30 tune.

Take a log when it happens, post it in the log review thread, and get others thoughts on it. You'll get a lot more information and responses with a posted log (from 2k-redline full throttle in 4th gear for auto) in the correct thread.
