These issues came about since fitting the 65mm pulley. Originally I didn't have the g40001 chip in and figured that was why these issues existed, however I've installed the new chip and the problems persist.
If you start it, then rev it to get rid of the battery light, let it settle back down to idle again, it sits at ~900rpm, then takes about a minute to die. I noticed after the first time it died, the rev counter kept jumping about bizarrely when the engine was off.
If you give it some gas and keep your foot in the same position, it will rev to 2000, die back to 900, back up to 3000 then die again.
Recently, it's had the supercharger serviced by myself,
new dizzy cap and rotor arm, as the last one was pitted,
New blue temp sensor a few months back,
Changed the co pot.
I've checked for vacuum and boost leaks, which seem to be nonexistant.
I'm sure I will have missed stuff out. Thanks for any help.
