MPE cold start sound. HELP!

twistedmunky · 07-16-2020, 01:58 AM

Hi everyone,

I have the MPE and a resonator delete on my F30 and have had a Stage 1 tune on it for the last 3 months. The cold start sound has been epic since the tune and I love it!

However, I have noticed in the last few days that the cold start sound sounds different then usual. The cold start sounds like a warm start now, but when I shut the engine off straight away and restart the engine, then the usual aggressive cold start sound reappears.

Has anyone encountered a similar problem? Or does anybody have any idea why this might be happening? Thanks everyone!

Not sure why that's happening, I would just try re-flashing the tune to see if that helps at all.
