Guys,

I need some help from you please.. I have a 2000 TT 225 quattro, APR chipped, T-Carbon FMIC,Neuspeed air filter, Schwing ****, Schwing Boost Controller BAMM,GFB Hybrid valve, Forge silicone hoses, 82* thermostat, Eisenmann race muffler.. and stock N75..

The problem is that I cannot go beyond 7-8 psi! Idont think I'mrunning on limb mode, otherwise the Ross-Tech Vag-Com will show it.

There was a slight leak on the pressure side that I repaired after running the log. I'm still getting the same boost reading with 3.5 full turns on the ****. At least, with APR chip, I should be already at least 1 bar gauge pressure already, so I'm expecting to see 14.5 psig on the boost gauge already at WOT on 3rd gear.. it's NOT happening.

Can someone tell me if the APR chip is not working as it's supposed to, looking at the Cmd Pressure, please?

Do I have a bad MAF? Anyone? Thank you so much.

well from that graph your maf sensor i would say is about 70 percent effective...get a new maf to start but that wont cure your boost issue....try unplugging the maf electical harness and see if it runs better....but i can tell from the numbers a new maf is needed

 

Thank you for your reply MeanAudiA6.

I have one question only please, by looking at the Cmd (Command) Pressure values: is the APR chip doing what it's supposed to do?

Cuz I had a problem with that chip and had to send it back to APR twice as I have 2 programs & my flipswitch was not functioning. I finally asked them to place Chipped program at slot no.1 (default) and Stock program at slot no.2 and so.. 2000 mbar absolute pressure above 2000 rpm sounds right though.
