HPFP and a tuning box & cable is still a cheap way to gain 100HP.

I believe it is, but it has had revised bearings to reduce the issues, and the 1.4 will have less torque (well unless you remap it), so should be less of an issue.
been reading up about it a lot.
More annoying is that it needs a HPFP mod before anything can be done. I seem to be gaining a shopping list
Or you could just enjoy it as it is, and then buy something better further down the line, if you still feel you need more power. I'm sure you've already been there with trying to make a car into something it's not - don't ruin an MPS as well please

It is criminal to buy an MPS and not tune it. The engine has so much more to give! Get on with it Diagro, do your usual.

Its rare to see unmodded ones
This one has a Jetex exhaust already. :O
Really you'll be looking at...

Theres a Groupbuy just started up over on MPSOC, 10 people need to sign up for $100 off

That seems to be the plan

Didn't see this...
No what is criminal is to buy an mps and hpfp then try and put a **** tuning box on it. I've not heard of one mps running a "box".
As I said elsewhere even professional places such as bbr, and the erm less professional like totalmps claim to be able to map these. There's been some horror stories.
Do it properly or don't bother tbh

My friend has just gone through exactly that with Justin. I have been doing all the logging for him, I must say I have been impressed with the service he has given my friend, it has been a breeze. He then got a decat too on his and it was no problem doing further tuning on it.

Still under warranty, no.
No warranty, hell yes!

Surely all the external box does is change the throttle map without affecting power?

No because newer ones plug in between the ECU and various sensors e.g. the MAP sensor and Boost sensor, they then "adjust" what the ECU is seeing, fooling the ECU into increasing the boost etc in order to bring it back into a "normal" state.
Personally don't think it's as safe or reliable as a remap (as you are already using some of the ECUs potential to correct faults, so if any actual correction was needed, the ECU may not be able to correct enough - e.g. not directly relevant but things like Fuel Trims only allow so much adjustment before they throw an EML).
Whilst it obviously doesn't require a detectable ECU flash, due to the amount of trickery involved, I would imagine an OBD tool (or certainly a manufacturer specific one) would show any historical sensor data as reporting incorrectly, and at least some questions could be raised e.g. by a Dealer.

I thought it was accepted that all/most of these tuning boxes were detectable if probed enough - I keep thinking about one for my m135, but the warranty issue (and insurance hike) is putting me off (I'm 99% sure it's known they flag the ecu as being "tampered" and this flag exists even after the box is removed - potentially nuking the warranty of any owners down the line too. I think some owners have suggested it's possible to code out this flag once the box is removed, but that's both specialist knowledge/tools and also there's still no guaranty). Afaik they tweak the inputs going into the ecu to fool it to produce more fuel/boost for the given conditions. While I could understand this could possibly go under the radar, but surely there would instantly be error codes/flags elsewhere in the ecu that the boost is now over the original (safe) parameters/limits, or any horsepower/performance feedback is above spec? Wouldn't any boost/hp gauge or even lamda sensor reflect the changes in the system and all potentially indicate it's out of manufacturer's spec? These tuning boxes are becoming more and more popular, so manufacturers (and insurers) are surely looking for them more closely - while the technician in the garage might not notice the error codes, I'm sure head office can probe the ecu and retrieve evidence of tampering a out of spec values if an expensive warranty job is on the cards?

I really like superchips remaps. They have a nice power curve and don't stress the car at all. They're somewhat expensive but you get great support.
I'm pretty sure BWMs have a hidden log file which tracks any ECU changes. A dealer (using the proper diagnostic kit, the super expensive stuff) is able to see when a car has been clocked for instance, because there is a separate internal counter which you can't see or change using 3rd party tools.

I'm sure it's not just bmw that have logs/measures to check tampering of the ecu or the signals (as I was trying to suggest in my post) - whether the input signals are "hidden" or not, it's surely easy to check whether the output of the motor is within the spec/performance intended from factory, or suddenly 20-40%/40-100 bhp more... Even if the box/tune is removed, it would surely have some historic error codes or logs of uncharacteristic performance out of spec.
