I would drive it hard using various configurations (like try upping the jet size while running 100%, try different threshold and gain, with and without the restrictor, etc.) I followed some other users' settings to get a baseline but every car is different.

I just got my intake valves checked after about 25k miles since the last one. All 25k have been with the hfs-3 doing its thing. The bad news is that there was still some carbon build up in two of the ports. The good news is that the build up was nowhere near as bad as after the first 25k miles. I drive the car hard as soon as it's warmed up, so it sprays quite a bit, but perhaps it's atomizing really well so it doesn't get much of a chance to wash over the valves? I'm also running 95% meth (after the meth tune) so maybe it would work better if the water ratio was higher?

In any case, after another round of walnut shells the beast has awoken once more. She pulls hard after 4k, just like I remember after Jan tuned it for meth. I guess the intake valves cleaning is just a necessity on these silly 56's.

Went to PMW in Miami and he told me not to bother with walnut shell blasting on the R53, I know you got a 56, but have you heard that to be true about the 53, carbon build up not so much an issue on the r53?

Yeah I've never heard of anybody needing to do it on the R53 and we've had our for 10 years.

I'm no expert but I'm pretty sure you don't need this silly walnut shell cleaning done on the R53 motors. The DI design of the R56 motors is what the problem is.

You just reminded me that I'm going to need to schedule another intake valve cleaning. Ugh.

Appreciate it fellas,
Sidebar question. If I may eventually get TVS, should I even bother with an aquamist hfs-3 because with the tvs I would do the w2a intercooler option.

Technical answer for walnut cleaning on the R56 is that it is a direct injection engine and has no fuel in the intake. The fuel in the intake is what usually washes deposits off of the valves which means the oil from the turbo blow-by is deposited and forms carbon build up. For the TVS, ask Jan about that, but I'm sure there will be a benefit to running meth with the TVS as there is with any boosted car.

You will still benefit. It has octane adding property's.
