Mclennans price for the remap etc was about £650, cm were 350, to be honest even though I have the smoke problem CM were great and so was the chap at angel, so I would recommend. The angel chaps coming to see me to turn down the map a bit too.
Car goes brilliantly now, smoke issue apart
I tried to reply to your PM but your inbox is full
Anyway, here's most of it:
I've been meaning to get in touch with you about how your remap is going…
I had similar problems as you last year with emissions. When I bought the car it failed MOT for emissions. The idling was terrible too. I eventually got the injectors reconditioned for around £650 (expensive from Argyle Diesel - just around the corner from CM).
It never fully cured the problem (still rough idling although not "as bad" and even went back in) until I eventually used a couple bottles of Redex Diesel Treatment. It run much much better and the idling is near perfect. What's more is I had my MOT done the end of Feb from CM and it passed at 0.04 now. Remember it failed last year and I still don't think the injectors were totally to blame/needed reconditioning.
Get something to clean to fuel system. Seriously, I didn't believe in that crap but now I'm using Millers Octane Bootser & Fuel Treatment (just started using it to try it). But these "additives" seem to help these cars. The only time mine smokes now is on startup when it's cold (but normal - something to do with not compensating for a cold start).
But keep me posted; I'm think as it's so "clean" now the CM & Angel map should be fine
