Lets see how good you are at the the mystic, I have 2002 s3 with supposed to be mtm bt conversion done by audi somewhere in scotland. The only identifieng numbers i can find on turbo are GGG3552 below that is 326 1016362F thats all i can find on it. Needless to say main audi stealers being less than helpfull same with previous owner problem im finding is lack of anything untill you hit 4000 where it just goes bonkers and takes off like a bat out of hell and doesnt stop till you run out of road, never tried it on a motorway just not got the bottle to keep it going untill i know its not going to keep going untill it goes bang. Surely it should have a decent response before 4000 fed up geting caught out pulling out and sitting waiting on it coming on power. Ive had it down at local mapper who does revo, he reported that when its on boost readings seem as would be expected with a big turbo but couldnt figure out why so laggie. So big question is does anyone know if this was done by audi to mtm spec what mapping would have been done so i can get it adjusted instead of it costing 500 bucks to have revo map done sureley this is possible. Any suggestions as to why so laggie and any remidies would be gratefully recieved. PS also running external wastegate, thanks in advance for any answers guys just cannot believe how laggie this car is .
