Fitted mine on Wednesday, really easy to fit only took 20 mins.
When I first started the car, the revs started climbing quite rapidly and when they were reaching 5k I bottled it and turned it off... Lol
Turned it back on again and the revs settled at 3k so left it running for about 15 mins and it dropped to 1750 rpm. Had to pick my daughter up and it was lashing with rain so didn't get chance to try it out properly but instantly you could tell the induction noise was slightly louder and throttle did seem ever so slightly improved but that could have been the placebo.
Most of my first journey was in 5pm rush hour so the car spent a lot if time idling at 1750, a few times it bounced around between 1500 and 2000.
Next journey was in the morning and was much the same although on a few occasions it was going up and down like it was thinking about it. on the journey home last night it started to settle more and more and this morning she was idling between 1000 and 1250.
Just been on a run and its a constant 1000.
First impression is a good one, induction noise is much more pronounced and throttle response is a bit better and it feels like there is a bit extra ooomph but not massive.
I think it was Litchy that said its "about the sum of all parts" and I would have to agree, its not a standalone mod but combined with everything else it makes it just that little bit better and a map would prob get the best out of it. That will come later with different induction set up but until then its staying on the car.
