Have you had car mapped since fitting 4bar regulator & S3 pump?
When I bought it, it was stg 1 revo with a 4 bar regulator, 2.5 years ago.
a few months back had noticed the pump taking longer to prime and getting noisy so got an s3 pump to replace it. Felt better since fitment.
Until a few weeks ago i was overtaking, as you do, and noticed a drop in power at 5k rpm ish... Logged next chance I had and found the injectors idc were sky high by 5k so now I have a wideband ready to be fitted when my 3 inch dp arrives, will stick that on the car and hook up the fuel pressure tester and take it a run... and will get to the bottom of it... Hope it's a simple one to fix...but I doubt it will be!
If the pump I recently bought is failing I won't be best pleased!!!
