I recently changed the plugs in my s2 rs and i thought i would pop them out and check the color to see how it was running and the tips were very white, witch to my understanding its under fueling.

Car idles fine but seems to hold back under boost, I do have a boost gauge and it seems to hold boost fine and i have checked for air leaks.

Car drives fine when not on boost 1st and second seem fine on boost but third and forth seems to hold back.

Question is that its seems like a mixture problem is there anyway i can increase the mixture slightly untill i get chance to get it set up propaly, Fuel pump seems fine and it buzz noise on start up..

I have read through some other posts about the TPS and have looked at mine and it seems to be all the way forward is this correct?

Thanks in advance for any replys

need it checking properly mate. It's running too lean, hence holding back.
