Ric

i checked yest and it has a 4bar. It's an early engine but with obd2 throttle and management. Still need to sort out fuel pump though. And yeah, just the z-eng chip i think. Will break out my cam at the weekend and post some pics.

Ok, so i moved the maf and air filter last night. Pulls much smoother and stronger below 3k, rockets up to the red line, and i saw an indicatated 30mpg on the way in to work today. Sweet.

my missus car had a similar issue, was a dead lambda so was running rich all the time. Worth a shot... Get it on a co2 meter or a VAG-COM that will tell you whats going on. Or, you might just be booting it more

cheers for the reply guys. Could be a boost leak i guess, i'll have a look at that tomorrow night. Will get the piping made up and give the DV a go. And yes, i think i'm still running a 3bar fpr. Worse than that, i think i'm still running a standard fuel pump from a 1.8 8v gti! Needless to say, i didn't build the car, just trying to sort out all the faults! haha. Does anyone on here go to no rice in fleet?

Just seen this thread. I have a z charger on obd2. At the moment my maf is after the charger and exactly as you said, it runs rich and is really jerky on part throttle and the fuel economy is awful (19mpg tops). So yesterday afternoon i had a play at relocating. Car was so much smoother and on my test run saw 30mpg. BUT... i think it might have been running lean as it didn't pull anywhere near as hard past 4k. It's probably a little closer than 8 inches and i didn't run a DV. Plus after putting VAG-Com on, i think my lamda is dead. So, 2 questions for anyone who's kind enough to answer:
