| My 996 ran like that when I had the 45mm Hacket chip in with the 50mm half system.
Silly really but did not want to miss the rideout with the Yorkshire boys so put the cans on in the morning thinking it would be ok.
Had peeps behind me dodging for cover as it kept spouting flames and banging like a good un.
Took it to Nellys who had the Hacket 5omm chip for me and put it in, set it up and it was fine, never popped or flamed once after that. |
