Got my new Ed 30 last Thursday. The guys at Superchips took the bluefin unit I had on my 2.0 TDI 140 (it was just (52 weeks old) under a year old) and reprogrammed it for my ed 30 - the cost just post and packaging ~£9 top guys, now that is what I can great customer service.
Installed on my ed 30 this weekend and it is awesome, I only have 300miles on the car so still taking it very gently, but basically as stock up to about 2800 rpm and then from this onwards the surge of power is fantastic.
Makes overtaking an absolute breeze. This is a very smooth map and initial impressions are that it is highly professional upgrade that provides supercar overtaking performance but in a very smooth controlled manner.
It feels similar in overtaking peformance to my tuned 993 (325bhp, 400nm normally aspirated, 0-60 4.8s, vmax 175mph - tested at elvington using ax22 datalogger) but delivered in a very progressive way. Exactly what I was looking for, 911 performance but in a Golf GTI package I am one very happy customer.
No affiliation just a happy customer who has got exactly what I was looking for.
