I have the GIAC normal map and hammer map, aswell as the Dbilas Intake and Milly Turboback. Replaced the Bluefin Map for a GIAC and instantly noticed a stronger top end. I've had it on the rollers at Awesome last summer and it made about 325bhp and 375Ibft of torque (seems too high to me). Drives very well, have had no issues whatsoever regarding the Map and exhaust.
Regarding the intake tho... the Dbilas is nice for sound... not loud like an open cone intake like Evoms or VF, but i do i get a nit of 'flutter and whooshing' noises on lift off at WOT. I like it, but the Dbilas intake on the edition 30 design is not the best, reason being, the diverter valve feed into the intake is placed right next to the brake resevoir, so without abit of DIY, it causes the brake n clutch pedals to vibrate.
I just had an autotech fuel pump done on Tuesday, unfortunately no one has ever had a pump fitted to an Edition30 with my ECU model, so i'm awaiting my customised software still. Even so, without fuel pump specific software the fuel pump has made the car alot more 'livelier.' Can't wait to get the new software. Hopefully get it on the rollers again to see what difference the pump makes.
