There used to be a 3 gauge pod for R33's, I got one for mine. I can't remember who, some business called Taikaka or something was doing them. It was years ago, sorry I can't be more exact....lost in the mists of time.
And yeah, re the EVC 5, what was once the cutting edge of boost management and getting the nest out of your turbo only 5 or 10 years ago [and which worked fine] are now outdone by the next big thing. But you can get some absolute bargains out there if you are willing to step back from 'modern'. I know my tuner keeps telling me to ditch my 7 for something better...…..but why, ok on a dyno it shows less response than a modern one, but it works fine on the open road, no lag or issues felt at all.
