Thanks Ben... Yeh i was but i dont think mapping is to blame for a conrod breaking or a rod bolt snapping...So i wont slag your knowledge either! Unless youre implying i mapped it to produce too much power
Both rod bolts have broken their heads off, but i dont know if they were the cause or the result of the rod breaking.

Its def onwards and upwards from here... Either a forged 1600cc or a us tall block. Dont really want to mess about with a zetec yet tbh!
