get the basic mods sorted first (exhaust and replacement filters / induciton) and then get the remap done....
Apols in advance to what has turned into another "watch out for AmD rant"...
I'm not sure about the new AmD sites sites, but the old AmD rolling road in Bicester was way out - massivley over-reads the torque, great for the ego, but dangerously misleading... they just seem to tweak the drivetrain drag / tyre settings and/or shift the whole torque curve to match what they think you want to see ....
After I'd spent about £1500 with them already (exhaust, front/rear brake kits, suspension brace and a few other bits) and then taken the car back for another £2k or so worth of mods (highlight cams, Koni/Eibach suspension and a few more) on my old Golf, they didn't bother doing the post rolling road session that they're promised (and was included in the price of the highlift cams!), but after they'd had the car for over a week, and I went to pick it up they said there had been a problem with the dyno, but "it should be fine": Pretty p!ssed off they didn;t tell me in advance that the work wasn;t finished yet... and I really wanted the dyno run as a health check, so I made the 4hr round-trip to get it done at another date nominated by them "when they were less busy", I left the car with them for 4hrs, after which they tried to palm me off with a generic dyno plot - nothing like the shape of how the torque curve felt or how the car was actually driving (they said it's be dead by 5800rpm and it was pulling firmly up to 6600rpm!), and they told me they were too busy for the rest of the day, so I'd have to bring it back another time, depsite knowing that I had a 4 hour round trip each time! I took it to two other rolling roads - the first one spotted that the fuel pressure regulator couldn't cope at the new higher revs and that the fueling was running lean and that I was only getting a fraction of the benefit from the highlift cams that I should have been... something AmD never spotted and I'd never have know about because they repeatedly reglected to do the dyno plot that they should have done.
The other rolling road figured weren't as flattering as AmD's (140bhp and 145bhp compared to the 148bhp that AmD said it was running at with a under-spec'd FPR).... and the later dyno's I got elsewhere actually matched how the car felt to drive...
AmD are well known, but I had such shoddy treatment from them, I doubt I'd bother if they were less than half their current prices... best value I've seen so far for a remap including before and after rolling road is £250 for the Chip'N'Spin rolling road (when part of a rolling road day) - that get's done on a "while you wait basis" and yes, it's about half the price of AmD's £380+VAT...
