Interested in end user reviews on the Z&F remap. I’ve read the articles / web links, so now thinking of upgrading without attending site by just advising what I have and few required parameters. Anyone done this and been pleasantly surprised by the result. What did you specify for yours (if anything) i.e. idle at 1K to illuminate 6 speed rattle (was 1k enough!), burble on overrun, and what’s the long term view on performance. In your opinion was it VFM? I’d probably pay the extra £60 for a straight swap and keep the old unit. I believe I would then be paying £279. Thanks, Bob
