My kjet abf seems to be ok at the mo,the 9a did pink on wot on hot summer days last year though, on the exact same setup on the exact same settings.. It absolutely rinses fuel, but to be fair it is overfuelling. The wur needs doing, and it stinks of fuel from the exhaust.. Going to set the pressures as per the wur mod guide, then weld a lambda boss on and use a wideband to check its ok at top end...it makes soooo much differnce to mpg when hammered tho, and I can't help hammering it.. Reading this back I can imagine I'm going to have probs in the summer, its overfuelling so I've got to back it off, but it pinked on the 9a as it is last year, so backing off the fuelling isnt going to help..hmmm....doh
