dude go to croydon, it took them 3 days to fit up my power fc d-jetro, wire in my new boost controller, do a oil change and a full tune, to me, thats pretty damn good, they didnt charge me over the moon and wer very very helpful with every thing i asked about and also gave me some good advice on where the car can improve but never ever pushed the sale of extra parts
if your going to whinge and bitch about how long a workshop takes to do the work then do it all yourself and then u will truely realise how long things take to do
