I fitted phase 2 chips recently to my mk 1 astra turbo. After a run, I let the car cool down and have noticed the revs will sit between 11 - 12 thou rpm for a good few minutes before settling at it's proper idle speed. anyone else with phase 2 chips experienced the same problem?
I had superchips fitted before and everything was ok except for the usual management light over boost warning.
any thoughts ?????
or is this the way the chips operate? checked for any air leaks and it's ok.
