Just an update guys, my car is going in for a dyno run at AMD next Saturday so i will post some figures, should be interesting to see what the mosselman tune achieves along with air filter, high flow exhaust and secondary cat delete.

I know that the mosselman tune from mstyle is expensive but it is well worth it, completely transforms the car and you can feel the manifold playing its part through the rev range. Iv never felt such a difference in a car through a remap, it just turns it into a complete beast.

Marc mine has started to use more and more oil as its millage increases. I usually have to do 1ltr every 5-10k miles of spirited driving atm, but that's a straight 6 BMW for you.

Having checked mine it was definitely worth walnut blasting... Its on my job list todo

I have a video of the black grunge that lines each of the valves.. must upload it at some point..

Also found a minor leak on the rocker cover gasket...

Mine made 213BHP with the 3 stage manifold fitted and 275 BHP after remap on the same RR on the same day with same ambient temps.

The 3 stage manifold prior to remap made the mid range throttle response feel nicer otherwise the car performed fine and I had no issues.

The car is night and day different to drive.

Where did you get the map done Will?

Mine only made 252BHP.

A 325i N53 should make 250-260BHP without the 3 stage manifold.

What was your before map number?

I didnt do a before map. I installed the mosselman map for the 3 stage intake tune but iv got a few bad injectors and black smoke so i think it may be related to that as i see a while ago someone had a n53 remap but was only getting 220bhp and it was related to injectors. Just wish i could find the thread again to double check.

Hi Will, how long did you run the 3 stage manifold before mapping? And did you have any issues whilst running the 3 stage manifold without the map? I have the 3 stage manifold installed at the moment but need to fix a Nox sensor before I get the map, and want to make sure I'm okay running the 3 stage manifold so I don't mess the car up!

Cheers,

H

From what I can remember from my research, it will run ok without the tune but the disa valves won't open at the right time and you won't gain much. I can't imagine it will do any damage though, the manifold would just be running at less optimal runner lengths.

Car will run fine with the manifold fitted unmapped... I ran it for 1 day and about 300 miles before mapping.

If you check INPA you will see that the DISA valve operating even without mapping. I do not believe mapping has any effect on DISA operations based on my limited experience on my car

Brilliant.

I can confirm it runs fine now as after your message I ran it for over a month without the tune!

I have now had the tune and have noticed a massive difference! I'm wondering if anyone has tested the 0-60 of one with the remap to see if it is close to 330 times? I'm going on the dyno soon (just been delayed after 2nd lockdown) but haven't got the gear to test 0-60s, and I've heard the GPS app ones are quite inaccurate!

Cheers,

H

Here's a question you guys seemed to have overlooked - why not just buy a 335 in the first place?

I mean it's 306hp straight out of the box with lots more torque (right where you need it too) and, being a turbo, has loads more potential to unlock (if you really must). Insurance will be straightforward too.

You'll save money and have a sellable asset when you decide to move it on.

Of course the elephant in the room is, what are you going to do with all this extra power? Traffic clogged roads and speed cameras on every bit of straight road kinda limit the opportunity to exploit what you have, never mind more power to play with.

Insurance and tax are vastly different- I have e91 325i and e90 335i also.. they are very different cars in many respects.
