Contact Difflow. They make a diffuser for the M12/m400 that looks much more aggressive than stock IMO.

- Chris

Thanks - helpful!

Strangely, I think this is the stock 3R Map.

The M400 map is supposed to be 1 BAR if I remember correctly. Amongst your many maps, do you know if there's a decent M400 one...

Fixed wastegate, checked ECU cables can read/write ECU files, and am now good to start some tuning.

Does anyone have a good M400 tuning file to start with? Car is an M12 with the larger M400...

Does anyone have a stock exhaust for sale?

Ideally downpipes and backwards. PM me.

- Chris

I might be interested! Sent you a PM!

You have a quick photo?

If there were no issues with functionality, I wouldn't care!

Car is finally boosting at its full potential. Momentarily spikes to <1 BAR, but holds to 0.77 Bar and depletes to 0.58 over the rev range.

Given I've got the car in a good running state, I've...

Found my culprit. After installing an AEM digital gauge, it appears the low pressure warning light is set at 10psi.

Normally I see 12-15psi at idle, but:

- Under heavy load
- High temperatures...

Yeah - would be great! I can pickup this weekend if needed.

Is the intercooler larger than the M12/M400 - if so I can pick it up locally.

Also interested in stock exhaust system!

- Chris

I mounted the Difflow diffuser yesterday (to align the holes 100% I chalked the frame rails which made the impression on the diffuser so no guesswork for drilling).

Looks sinister, perfect fitment...

Any photos / price /details?

Looking to upgrade to a 3" Stainless System for an M12/M400 (Its an M12 with the T28 turbos):

I've heard a few options are available:
(1) Hoover's
(2) BCS
(3) Rousch
(4) H&S

Anymore come to...

Does anyone know the sizes of these fittings or where to locate?

They go from the oil pressure 90 degree fitting into the engine bung using these two items:

Sure - by blueprint is this a dimensioned drawing or CAD file? Feel free to send my way @ colemanmit@gmail.com

In the last photo you can see post-Alcantara covering.

Here's prototype #1 (not yet covered in Alcantara). Will try another version which blocks less of the tachometer.

Hey guys -

3d printing a gauge mount for the steering column to hold two gauges, I'll put my Noble oil pressure/temperature gauge there as well as AEM AFR gauge

Will then cover in black...

Its synthetic.

- Chris

I'm seeing:

(1) 10-12 psi at idle
(2) 35-40 psi at 2500-3000 rpm
(3) 50-60 psi at WOT

The gauge does fluctuate a bit (+/-3 psi under load at higher rpm). Conditions for reference:

- 105...

Can anyone give me an approximate range of pressures to expect across the rev-range. Normally I've heard 10psi per 1000 rpm's as a rough rule of thumb.

Additionally, I've bought a more...
