Update
I have had the Autotech hpfp and camshaft follower lobe changed,
I had some issues with uneven acceleration and lagging power, which seem to have been resolved, The car generally seems more responsive and smoother.
The old follower lobe that came out seems to have bulged outwards. The new one had a flat base.
Hoping car stays as it is.
Are there any major issues to look out for regarding using Autotch hpfp's.
Thanks for all your comments and advice.
