When accelerating the car hesitates for a second and power comes back on and the same happens again within a second or 2.
With the help of StevenL we did a MAF log and below is the result. Any ideas what could be causing the drop in power.  MAF DV Nothing came up on a scan for errors in the car. -------------------- Mine - 04 Cupra R

It looks like its closing the throttle as the ecu doesnt like whats happening . Go To Adaptions , put in 000 and save , this will clear the adaptions . Can you log the "throttle butterfly " position ?

When we went into adaptions and tried to change the value in channel 1 to 000 it would not let us save. The rev's would drop slightly but no save option? Wrong place? Also, where would we be able to run the throttle butterfly position. -------------------- Mine - 04 Cupra R

ChippedIre Ment for you to use channel 000 for adaptation,This erases learned values
