That is both what I wanted to hear and didn't want to hear!! Thank you
Which part is bad news?
If your at about 185k on that engine, I think you'll be lucky to get about 235ish at the wheels, a remap may bring it up to about 250. Of course there are unicorns within the Zed world. Some have had basic breather mods such as an exhaust and a filter and had over 300 at the wheels which is remarkable, others which plenum spacers etc have only seen up to stock number or lower.
Every car is different and maybe about 1% of Zed owners (350's) know exactly how the car has been driven because the rest of us bought second hand. The harder its driven the more power it loses, the longer its driven the more power it loses.
I haven't got the UpRev yet, but it's certainly high on my list due to what i've heard from people on here. The Zed is the most powerful car i've owned and the best to drive, so I can only imagine how great it'll be after a new mapping
Ref the fuel debate crap: I don't think anyone has mentioned anything negative about 97 ron, it's perfectly acceptable, and I have no idea why the Zed can't detect knock over 3500/5000 rpm, whichever it is, but apparently thats how it is I'm not taking the chance for the sake of £5 a month.
