....I have no reason to doubt PDT's advice/opinions because I don't know them. But I know JKM very well indeed and am always inclined to take their advice. So, if I was to ever get an HPFP (highly unlikely as I'm happy at Stage2), it would be an APR.
JKM advised me against fitting the Autotech internals but I ignored them. It was a humbling experience limping my car up to their front door and having to leave it there for a few days for the APR pump that they ordered for me to come through
If you are thinking of spending extra money on the APR fuel pump, I would not bother as its wasted money.
I guess the viewpoint of wasting money depends where you stand - my £250 Autotech internals and about £80 OEM pump wasn't worth much after that!
In fairness, my Autotech pump lasted fairly well but my map was only requesting stock fuel rail pressure. When I went Revo and got the full 130 bar of rail pressure, the pump lasted only a week or so before blowing the seal in the OEM pump housing. I have been running the APR for 30k miles now without a problem.
Fair do's to those running the Autotech internals and doing OK as I have nothing against it despite my experience - most have been lucky; others like me have not.
