1stly dont use Angel Tuning they tune the car to a unrealistic point where the cars clutch just wont handle it (the max they should boost it is by 30BHP no more, not the stated 50BHP, thats just to draw people in thinking there Bravo is 150BHP when on the rolling road its way off) and 2ndly if the flywheel needs to be changed aswell as the clutch then your talking mega bucks. I think the fly wheel is £300 to £400 on its own.
If you get a remap get a custom one and a remap that can cope with the clutch. Dont pay for a remap that just plugs in and transfers a map to the car in 5mins. Afterall what Bravo JTD is the same. I.e The map they use could be from a JTD that may have non OE fiat parts, exhaust, MAF etc, when was it last serviced, what was the mileage of the car etc etc, get a custom map, specifically suited to your car. Try red dot or celtic tuning maybe a bit more expensive but offer full VAT receipts unlike Angel, still waiting for my receipt over 7months now. The other companies offer very reasonable prices and do custom remaps and i think red dot offers rolling road genuine BHP outputs too.
I had my clutch done locally, cost me £370 its an 8hr job, had a Valeo 3 Piece clutch fitted with 2yr warranty. So take it somewhere you trust to put it all back together properly for you. Sub Frames etc need removing.
Clutch just couldn't hold the power.
