Tbh i don't know what to do,at the moment it is a pig to drive sometimes.

Even if you manage to fix the midrange AFR with the afpr you will be making the car too rich at all the other rpms where it currently isn't too lean.

Btw, did you say you have an upgraded fuel pump yet? If not then get that done.

Also, I see you're in the uk. I have a Dastek uniQ piggyback for 100 pounds if you want to tune the car properly.

For sure you would gain some hp being tuned vs untuned. I know there are Dastek tuners in the uk, hence my suggestion. It also lets you run up to 5 different maps. Installation requires splicing into about 6 wires on your ecu harness. Drop me a pm with your email address if you wish to discuss further.
