black means unburnt fuel, it might be running a bit rich - get the fuelling checked out by an expert on a rolling road!!!

Noooooooooooooooo!!!!!!!!!! never in a modded saph cossie mate, they have been known to melt in higher big bhp cars, the c57s have a better heat range.

As said prob over fueling, gotta get mine done as their the same and u can blatently tell its overfueling cos u can smell its running rich by the fumes.

Really? Not suitable for a Stg one then?? Should I consider the C58c's?

Ermmm check with stu mate, stage 1 should be ok thou but i know he said their a big no no on a stage 3 set up.

Infact just re-read it and realised he said its a stage 1 aswell but as said double check with Stu or someone!

um....59s are FAR better in mine than 57s!!!57s misfire ALL the time,on start up,on motorways if just driving normally!they even stopped my car from starting a few times as the gaps closed up and they wouldnt fire!!!59s much much much better in my experience!
