Are you running an uprated FMIC?
Yup - I had one on my m135i [Wagner Comp evo 2] - only changed it once I ran my Jb4 at higher boost psi with octane booster ie map 5 and map 7. Heatsoak was very noticeable. From my experience of Jb4 m135i in UK climate OE FMIC is fine upto ~ 16psi.

It's worth noting that p/backs work differently to remaps as they fool DME into providing more boost. Whereas OBD remaps are more sophisticated, in that can get similar gains c/w lower boost levels. Heat management is a common issue though, hence higher flo DP will always be a given - to keep EGT's in check and reduce thermal stress on turbo - I'd be willing to bet FMIC upgrade is 'CYA' by tuners and slant to get us to spend more £££ on bolt-ons.....
Looks like I might have to invest in a front mount :lol:

And what is the risk of it turning your car into a large brick, just don't want to get it wrong :lol:
Risk is low as

1. you can log data with MHD app on yr android to see how yr car is behaving.
2. Heatsoak is well monitored/managed by ECU

If you experience a lot of heatsoak - which I doubt here in the UK and want to mitigate ECU intervention then you can decide if you want to install upgraded FMIC or stay as-is.

Be warned thou - not all FMIC are created equally some may weight a ton, some have great heat transfer but rubbish pressure delta across inlet to outlet so whilst yr IAT's look great the lag is will grate after a while....

Thanks for the help :) I was thinking of buying the Amazon Fire 7 tablet and leaving it mounted in the car for gauges, any idea if it will support the MHD app and cable? Can't find out anywhere if it will! Sorry to be a pain!

If yr Amazon Fire 7 can see google play store then you should be fine to download MHD app. Cables - you need OBD/KDAN to USB cable in from OBD port via a normal OTG cable to connect to tablet.

What K+DCAN cable did you use, and will it cancel the warning light from the high flow cat?

Been running this for a few weeks. Highly recommended

Stage 2+ is an absolute animal
How is it going at the moment? Found any flaws yet?

Is that 102 RON? Where are you filling up with 102 RON? lol. Ever had it dyno'd?

I have dragy ready to log some performance data for you....
