Soooo,   Ive recently just got myself an octavia vrs 1.8T on an 03, having a bit of a problem with it...

 

Everytime I turn the boost above 1 bar, it goes into limp mode, the cars had a custom map.  Plugged it into VAGCOM, and it says boost limit exceeded.  Ive replaced the MAF, The MAP sensor and tried clamping the MAP sensor today with both 4.3v and 4.7 v diodes without success.

 

Please help me <img data-cke-saved-src="http://www.briskoda.net/forums/public/style_emoticons/default/emoticon-0106-crying.gif" src="http://www.briskoda.net/forums/public/style_emoticons/default/emoticon-0106-crying.gif" class="bbc_emoticon" alt=":" ('="" style="border: 0px;"> lol

 

The cars had the following: Fully forged internals, forge motorsport intercooler, forge 008 dv, forge pipework, full stainless 3" system turbo back, N75 DELETE, MBC, N249 Delete
