How much to tune a 01 bmw 325i turbo do you gys tune ms43
Maximum PSI out at Pocono Raceway for some racing..

FULL SEND! While it may have snapped an axle on this pass, Mike from Maximum PSI never disappoints....

1## 6-speed manual, Twin Turbo E46 M3 shooting for 8s in 2020, stay tuned.
I have a friend with an E46 M3, and I am planning on getting one. Your website does not list the E46 M3 turbo kit. Is this still offered??
BMW M4 gettin dynoed, fully built. Owner

Built by Maximum PSI
Bought a car that has a kit from you guys I ended up building the engine going aem and I’m wanting to make than 800 hp what turbo would you recommend to run on the t4 manifold
This customer came to us in search of more power from his F80 M3 and these motors are capable of loads, but……….……if you’ve been following the S55 motor then you are more than aware of the flaws when cranking up the power. The main culprit being the crankshaft hub and achievable clamping force of the factory bolt and assembly. The original flawed design allows the timing gear to spin independently from the crankshaft, especially when the motor is modified to produce higher power levels. The best case scenario when a “crank hub” spins independently of the timing gear is the motor runs poorly and needs to be re-timed with new components. The worst case, the valves contact the pistons requiring a complete overhaul and/or engine replacement.

The solution we turn to over and over again is a keyed crankhub and timing gear combo, this one is made by Maximum PSI. This piece is a tried and true method of joining the three separate gears by means of keyways and pins. The installation of this new assembly requires holes be drilled into the factory crankshaft and is definitely not for the faint of heart. The result is a beefy assembly capable of handling all the power you can throw at it.

This customer is already testing e30 fuel mixtures and is more than happen with the added power and piece of mind he gets from his installation.

Congratulations Maximum PSI for setting a new world record with the F80 BMW platform, 9.352 @ 151MPH!!! 🔥Check out all their amazing runs 🔻

Using 10-Plate Sportsman's Plus Clutch

Record captured by: Talontsi97 Videos
While walking around the park, a gentleman asked us to help guide his immaculate 2006 BMW E46 M3 up on the trailer.

After helping him get it on the trailer, we found out it only had 9,200 miles. 😯

Not only that, but we were told it was equipped with a Maximum PSI Stage 2+ Turbo Kit running a 6266 DBB Precision Turbo on 🌽 E85 Ethanol Fuel. 🤤

Let’s not even mention the flawless BBS Wheels , roll cage, suspension bits, or interior setup! 👌

MHD Flasher N54 V3.00

You've been asking and today we deliver! Through no small feat of engineering, we've been able to bring our whole MHD+ suite to the N54!

This includes:
- flash only antilag (no hardware required)
- on the fly map switching with up to 4 map slots (OTS coming very soon)
- updated FlexFuel including support for CANBUS based Ethanol Content Analyzers (ECA), while still supporting the existing Motiv N54 FlexFuel kit
- advanced 2-way Motiv Re|Flex integration, with PI safety (limp on PI injector failure), ability to log ReFlex data right in MHD, and output of WGDC to ReFlex for external wastegate control, all over CANBUS
- fully custom boost control and WGDC control schemes to help simplify tuner's lives when tuning past the OEM TMAP limits

To use antilag, make sure the car is up to operating temp and press and hold either VOL DOWN or pull the cruise control stalk in towards you (DSC must be one press or full off). Slowly ramp into full throttle, and after 1-2 seconds of building boost, release VOL DOWN or the cruise stalk.

To use mapswitch, you can use the method many are familiar with by pressing VOL DOWN + CH DOWN at the same time and release (or you can hold the TIP button on cruise stalk for 2 seconds). CEL will begin to blink and RPM needle will indicate current map. Change the map selection via CH UP / DOWN, or cruise stalk UP / DOWN. To exit, press and hold the TIP button on cruise stalk for 2 seconds or press VOL DOWN and release.

Until the OTS multimap release, mapswitching is for custom tunes only. Our public GitHub has been updated with the appropriate XDFs. Additionally, the MHD+ Suite: Tuning Guide has also been updated and added.

We kindly ask everybody to read the user guide to learn how to use the latest features MHD offers:

We hope you enjoy, and check back very soon for the OTS multimap update :)


Just need to get that 60 back down. New personal ET record. One tenth off world record. New mph record.

Every pass gained a little bit. Have to fox turbo outlet charge pipe as it blew off 3x. Clutche are right on the edge of holding on. Def has 8 second pass in it with some tweaks. Great first day at the drag strip for the blue car. [email protected] all boost no nitrous, no anti lag.

Gotta love the continual updates to the BM3 platform!

Electronic Wastegate (EWG) Disable is one of the cool new features in the next bootmod3 release. Currently tested on the S55 with on Brandon and Ben’s badass S55 builds. Going with aftermarket big turbo kits where the factory EWG (Electronic Wastegate) controller is being removed in favour of the conventional wastegate (e.g. Tial, Turbosmart, etc) for boost control. EWG OEM setup is great but this option makes it much easier for custom tuners to dial in your big turbo setup and focus on what matters most, making gains 💪💪We have the changes in testing for the B58 with as well which will also apply to the A90 Supra customers going BIG soon🔥More feature updates to follow soon
