Stuttering

[gazzrazz]

I have a problem post remap with my cupra. basically in normal driving conditions it is fine however when you really put your foot down the car feels like it is skipping along its really hard to explain but like its accelerating, then thinking for a second, then accelerating again. it doesnt seem to lose power and the speed is still riring as it should. just more annoying relly feels like im driving on water going over waves. sorry for the rant but ideas would be great....

cheers

could be a coil pack perhaps or at least the startings of a coil pack going

check for any boost leaks, check the DV and check all pipe work

by the way "driving on water going over waves" I think has been the worst analogy I have ever seen on this forum! lol!!

Try a search for surging.

Is that what you mean?

from doing a search ive found that it looks like the N75 valve. so my question is which variant of the valve do i need is it the N75 J? my car is a 2004 leon cupra 180 remapped to 225BHP.
