The IDC is at 42% at 6700rpm.

I get what you saying. I dont have the injector duty logs from the tuner on me currently. I will run a log and advise on what duty cycle the injectors are on by this morning.

The car is going into a fully forged motor with a big turbo build in the near future. I asked the tuner if we could go bigger than 550cc and probably tune for what we need so we dont have to change later on again. Price between 550cc and 1000cc (980) was like 20% difference in price here.

Hi Tuffty Front wheel dyno with Haldex disconnected.

Just to add on we have also fitted a brand new bosch b1s1 O2 sensor. Although the lamda readings for fuelling looks fine. the plugs are getting white as it would be if the car is leaning out.

Hi Guys. I have Audi S3 8l with a stock motor with below mods: 80mm forge tip with K&N cone filter. 3" catless downpipe. 3" catback exhaust without resonator box. 450lph 5 bar intank fuel pump. 1000cc bosch injectors. r8 new coilpacks. I have sent the car to a well known tuner in SA for a...

Hey guys. A update on my overboosting issue. So after the replacement of my turbo, on wastegate only, the car holds at 0.5bar throughout the rpm range. But with n75 plugged. I am getting overboosting issues. I have a new oem turbo and actuator fitted. A new agent n75 valve fitted. A new agent...

Just an update. fitted the new original Borg warner K04-023 turbo. Took it for its first drive, it spiked hard to 1.6bar on first gear. I have not had a chance to confirm wastegate pressure, I will take it for a drive with n75 electronically disconnected to see what we get. Will keep you updated.

Guess will need to just fit it and then test and confirm for now.

Whats the chances that my brand new original Borg warner K04-023 turbo having a boost creep issue also? Porting a brand new turbo will void the warranty. Not sure if it is worth it though. Just dont want to do all the work to fit the new turbo on and end up with the exact same issues. Anyone...

Thanks. Will let yourl know if the replacement fixes my issues.

Thanks bud. I am not sure of the authenticity of the guy either. At first it did not make sense to me either, so thought maybe someone else experienced it before. I bought a new borg warner oem turbo with actuator. Once my gaskets arrive from Audi, will fit it on and hopefully fix my boost...

I have been chatting to some people as I am out of ideas on whats causing the bad boost creep on my S3 8l. I have heard something that no one mentioned before, if you have a larger 3" downpipe, it can cause boost creep on a K04-023 original borg warner turbo. I have a brand new original borg...

Yeah sorry I removed the actuator off the turbo. Please view actuator pictures. If the bad boost creep is not the turbo, guess Im at a loss at what causing the issue.

More info. Initally thought it was overboost so have changed actuator, n75 valve, map sensor and all vacuum piping to DV and from N75 to wastegate but the same issue remains. I have electronically disconnected the n75 valve and the car boost to 0.5bar but increases as the RPM climbs. Same...
