Hi,

Been following this forum for over a year now and would like to thank you all for sharing so much useful info. Also i am completely new in this stuff so please be patient with me. Cheesy

Recently i went for a remap Stage 2 (SEDOX tuner). It was flashed via OBD. I noticed the sudden drop in boost in 4th, 5th and 6th gear on WOT reaching around 5.5-6k rpm. This does not happen in 1st-2nd-3rd gear. I have VCDS log of 4th gear pull and hexdump of the ECU.

Another thing, i have learned how to align map packs on stock ECU files but i am having problems doing this on my tuned ECU. Is it something i am missing. Are the both maps (stock and stage2) currently on my ECU?

My car is 2006. MK5 GTI 2.0TFSI BWA MED9.1



Many thanks!

It drops requested load thus the boost drop. Could be knock or component protection. Log 001, 003, 020 and 032.

In VCDS yes. Ensure you use turbo mode. The block numbers you need to log are in my previous reply
