Let customers speak for us
Truly unlocks the sound of the B58! The installation took a total of 40 minutes and fit like a glove. I couldn’t be happier with the results and will definitely do lots more business with MRM.The customer support they offer is second to none! They make you feel safe and secure about ordering and are ready answer any questions you have. I can’t recommend this company and product enough. Thank you MRM for your top tier service.
Easy install, and work great! Look nice as well.
Perfect fit, silent operation (compared to the OG Dorch that I had before) and enough fuel to run my b58 stock turbo full tilt on E50 with fuel to spare.
ZERO problems and wicked fast compared to the gen1 hpfp (with the proper tuning of corse)
The intercooler is great. Arm did a great job with this intercooler. The Intercooler is not stepped like the VRSF but the fittings and quality in my opinion is much nicer.
Great quality and great fitment Downpipe. Huge gains, the best engine mod for the n20 for sure. Make sure you order new Exhaust clamps and turbo band and seal. A lot of the time they have to be cut off. One thing that would be nice would be for it to mount to where the old catalytic converter mounted to like The ER Down pipes. However for the price compared to the ER Dps the VRSF are definitely worth it.
Bootmod3 is great for making more power. the interface is super easy to change the settings the way you want them. It also gives you options for Down pipes and disabling the o2 sensor.
MRM goes above and beyond and checks the Fuel Pumps for damage and wraps them in bubble wrap to protect them in the box during shipping. Very happy with the service.
Huge upgrade. Running Full e85 big turbo on a BMW N20. Fueling started to become an issue, this fuel pump was an enormous fueling upgrade.
I love the 5" dp, pending install but I have heard it give sthe b58 a deeper tone and fast shipping too ofc, but overall great product, alot more ppl should know about this product.
Arrived in OEM packaging after about a week. Bosch box was opened, but pump appeared to be authentic, brand new and unused. Put about 1k miles on the pump and its working fine and supporting additional ethanol just fine.
Easy to install and great hp and tq gains. I would highly recommend to anyone who is looking for a power bump!
Smooth purchase. Product as advertised. Thanks!
