Im going to tackle the boost return mod soon and was wondering, how much PTFE spray should I use in my old charger [which is going to be full of that bog standard oily pish]??
I understand you spray it for 2secs every 1000miles or so, but is the initial amount any different?
Do I need to drain any of the oil that will already be in the charger?
Then, how much will i spray into my new freshly built charger since it has nothing inside to lubricate it?
Cheers, Adrian
