they look like they are linked to you replacing the lambda? You tried clearing them and seeing if they come back?

yer i cleared them when i changed the turbo over but it come back again i think it went into limp mode  earlier to as it wouldnt boost past 10psi but now i cleared it its boosting to 20psi again

k03-052 (k03s) stage 2 rtech but it not custom nick come down and loaded it on which he dont do no more..

i boost leak tested it to had a slight leak on the one pipe on the n75 and on the tip on the turbo so sorted them will see if that has sorted it

i also cleaned off a load of sensors lambda sensor intake sensor throttle body

im wondering if with the k04 now on there and the injectors on there limit on a stage 2 k03s setup now with the k04 it cant cope

i would guess nick would know if that could be my problem

You dont need to buy a kit. a few plumbing bits and a shrader valve does the trick (And a compressor with tyre inflater). You just need a end cap that fits in where your maf connects to the TIP.

i thought of doing that but i just thought for the price of the kit it saved me the hassle
