M135i Bhp boost?

[EloisaT]

Hi. I'm new to here so apologies if this is regularly covered but I've just bought a 65 plate m135i and as much as I am in no way bored of the power or driving thrills yet, id like to know what power upgrades are available. I've seen 380bhp is achievable. Anyone have any experience or info on whether I should go and what I should have done? Thanks in advance.

Absolutely zero experience of BMW's here but the guy who mapped my Saab also does the 135i and gets decent results, around 400bhp & 450ft/lbs from a remap!! Has an excellent rep with the Saab tuning

Really impressed with mine, looks like he maps them he same as the Saab with the iflash, and Martin93t on UKSaabs and VXROL is the UK distributor for JZW.

You'd have to register on UKsaabs to contact him though (he might also be on some BMW forums?) I'm meeting him tomorrow so can ask him for a price if you like?

This the reader thread so you have to post picture up, that is the law

You will get a better answer on the BMW 'M' section on here, but I think Evolve or Birds are the ones to see.

JB4 is what you're after.

Do a quick Google for JB4 and it will pull up what you're after.

Do you have the N54 or N55 engine?

A few hundred quid will get you to around 380 / 400 bhp
