First - Star performance are good guys to deal with. Used their rolling road, very friendly, professional, you'll get a decent job done there, but it's a bit of a trek if you live in England so figure in the cost of a tank and a half of juice to get there and back.
MRC tuning has been around for a while - any Audi S2 with any decent power across Europe (
www.s2forum.com) has *probably* been tuned by the 'MRC' guy, so near enough all of the guys on the S2 forum know him, and I dare say on the RS246 forum too. At the moment they are setting up premises in the UK - Rolling Road etc, but that's taking time, so till then they are touring about, remapping cars several at a time. There were about 8 or 9 cars there when I had mine done on Saturday (met up at one of the guys' houses, there were like 6-7 Audis outside, my Seat, a Clio, a Lupo GTi, Golf Mk2 1.8T, sort of a car lot!) so right now it's not ideal, but at least they show willing by coming to you.
They remapped my Audi for me when I had it (somewhere between 350 and 400hp - the full boost never came in on the Rolling road, but was fine out on the street @2 bar) so did mine for a 'special' price. Best thing to do is email/call and find out what they can do (I don't work for them, I just know they are great at what they do, friendly, and they all have tuned cars themselves. One of them has a 1.8T golf tuned from 150hp to 225hp and 258lb ft or thereabouts, and a very very fast Audi S2, another has Audi S4 etc).
Right now MRC are 'based' in Scotland from one of the guys' houses until the Rolling Road/Premises thing can be sorted out. Like I say, they've been around for years, but they do their own mapping specifically for each car dependent on Mods, and have recently decided to go down the Rolling Road route here in the UK.
Phew!
By the way, I am NOT connected in any way to these guys - I've tried to be impartial and tell it how it is!
I'll see if I can get in touch and get one to post on the board to answer questions if need be - I can still contact them through my S2 Forum membership mail. There are some prices on the website I believe, but it's always worth trying for a 'group' discount (not just with car tuning, with anything
) I guess.
Cheers
