I've heard of 1 or 2 cases where the H as caused limp mode but haven't heard of it happening with the J.

You can get limp mode with a J if you put it the wrong way round.

Yep but before it hits limp mode you get superfast spool-up and LOTS of boost! :eek:

Briskoda RR day with a N75J fitted

UKMKIVs RR day 1 week later with the stock N75F refitted

Note James' comment on the second plot after telling me off the previous week for playing around with N75 valves!!

For sure.

so looking at the above plots for a modded 1.8T its not worth running BUT is it worth running one on a standard mapped car?
