    Thanks bill. Not sure but will ask around. Failing that I know AMD do them and they're 30mins away. Many thanks team!

    Hi guys. Sorry to bump this and this is by no means me arguing!!

    However, after eking told AMd don't do testing at weekends (I can't do weekdays) I contacted a local specialist called Peter Norris. They told me that a boost leak would show up on the dash as an error. But he also stated that if the car wasn't boosting I would need a new turbo. If the car drives fine, I'm chasing ghosts and should save myself some money...

    I presume that is just a lack of understanding??

    Will only show up on the dash if the long term trim is pulling 25% or more fuel out to compensate... I would not bother going to 'that' garage based on that advice...

    Get yer arse down to Glos and let Bill have a look

    My next phone call!! Worried that AMD have just fitted the TIP badly. The car made 225.7 on their rolling road, but then 240 after a map and having the TIP fitted... Cheers again PAul.

    Sorted. Finally! Went out with a local audi knowledge bank logging the car. Saw about 204g/s. didn't think it looked like a boost leak as was holding steady. Decided to change the maf for a spare he had (from his 500whp b5 s4!!!) and voila! First run saw 223.3g/s!

    So Bill, if you're reading this, thats 279 indicated hp from VCDS logging on an AMD mapped car with b5 tip v1 and Jetex!!

    I'll get some logs when my lead is returned to me.
