I'm totally getting that it's the response, low lag, quick spool up etc that these turbo packages deliver, and I know everyone who now has one or switched to one from other turbos praises them as well.
But has anyone noticed a difference performance wise?
Any of your customers ran quicker or slower times on the quarter Mark after switching turbos to an efr?
As Mark said that's all he's sold these past 5 years and I know cossies are not as common anymore it's just I'm yet to see any deliver good performance or stats compared to the 'old' technology....
Anyone out there know/experienced different??
Anyone using an efr on level 8 or P8??
