Anyone tried VP MS109 race fuel running with apr 104 file?
i found that after a couple of runs,the ecu request boost drop from 1.5 to 1.3 bar, and the fuel trim was as high as +15% , looks like engine is running too lean
any idea why ecu decrease the request boost ?
weird "dang dang " noise from HPFP;
just replace the hpfp cam follower, when i start the engine, the hpfp comes a strange "dang dang dang" metal knocking sounds, it last for seconds and then gone.
is this normal as i just replace the cam follower , or any potential issues may have?
Thanks for...
just replace spark plugs ,and re-gap them.
got a issue of idle misfire on Cylinder No 3,
misfire happened only on idle, no single misfire on full acceleration from 2000 to 6000 RPM
bad spark plug or wrong gap (maybe too small?)?
what do you think
how do you think of this

plan to try it as boost is a little bit lower than when turbo is just installed
Max n75 duty cycle i have seen:
my car is 94.9%
mk6 gti with apr k04 is about 98.3%
Golf mk6 R is about 98.8%
my old 1.8t is 99.9%
are these hardware limit or software(tune) limit?
just want to do a little fine tune of K04 file which is to lower the output in 1st gear which means less tire spins in launch ,APR K04 V3.1 just does it
Is it easy for tuners to add this feature?
any harmful or damage will bring to turbo or engine if I installed the threaded pcv tap plug for years?
this:

Parts no 9 :PCV tap plug
Apr only recommend install that parts temporary
Hear "ca ca ca" around 4K rpm, sounds like DV is working not allowing boost pass 1.5 Bar or Leakage..
i'd like to log to find out if it is by design or somewhere is leakage
any suggestion?
