So after a traumatic day today I thought I'd start a thread to keep all my work in one place, its going to be a little slow, hopefully useful and definatly painful!
Having recently bought an s3 after years of a3 ownership I thought I'd start as I mean to go on and get a Badger 5 Revo map, I thought the car was running ok, logs looked ok, car felt ok. Epic fail!!! First off there was a couple of vac leaks, fixed them up and straight on to the rolling road. Well chuffed as it hit 209.6 bhp which bearing in mind its a ten year old car which started as 210 bhp ( APY ) I was well happy and excited and looking forward to the mapping.
This is where it went badly down hill, by run 3 it looked like the maf is buggered. After pestering Bill we decided to put a basic stage 1 stock Revo map on the car with the boost wound down, RR it and it ended up showing 166bhp Gutted!!!!! Turns out I also have some serious fuelling issues ( running massively lean ) and some very very odd timing results which even Bill didn;t have a definative answer for ( blocks of 7.5 ).
After 5 very cold hours there, kept warm by coffee Bill managed to get it running at 225 and with an extra 40lbs torque.... Even with stage 0.25 lol the car still feels much better. As soon as I've got my act together and fixed many things I'll be back up to get it finished, then I might have some better figures! Bill was very patient and did a good job of making the most of the mess of a car I gave him, can't wait to get back and have the rest....
So lesson learnt, check everything on your car before you declare it as sound. My shopping list has changed a bit it was
xs power manifold
fmic etc etc
Probaly fuel pump
Silicone vac pipeing
Rear brake discs and pads
Everything will be photographed and updated and it may even get interesting with a hybrid turbo at some point in the nearish future.....
