The next time I'm contemplating a high speed chase, or a high speed anything I'll remember that. Meanwhile, I'm going to enjoy being able to just jump in the car, start it, and drive it. No waiting, no funny noises from compressors, no ups, no downs, no tilting, no light shows, just in, start, drive.
When I said there might be a bit more of a roll it is so slight it's hard to notice.
Anyway, job done, I'm happy, the devil may care, but I don't.
Thanks everyone for your input.
PS If coils are so dangerous (were all going to die) why are they still on sale from reputable companies, (made especially for the job) and why do so many LR and RR owners fit them? Perhaps the diehards should try to get them banned.
