I have a 1.8T AUQ with Revo stg2 map, dont think its been running right for a while as i drove my mates Revo stg2 and was like a different beast :-( It just doesnt seem smooth and sort of bogs down mostly coming on to boost. Just doesnt feel nice to drive. Somtimes it feels as if ive dipped the clutch and just cuts and off again. I have connected a fuel pressure gauge inline and is showing 3.5 Bar rising to 4bar when vac line off FPR. So far i have changed --- MAF(less than 12 months old genuine from ECP) - CTS(Genuine few months old)- N75 (Genuine)- 2.0 TFSI coils- Full coilpack loom- Injector seats -----I have made a boost leak tester and found some leaks, Injector seats and pancake pipe which ive now sorted(I think). No longer hear any hissing when pressurised to around 15PSI. When driving the car, if i drop my right foot i can hear the turbo whistle but also a hissing sound? What could this be? I have VCDS and a boost leak tester so if anyone has any tests i can do it would be much appreciated
