Aquamist HFS-3 and MINI Tank GB

[silhouette88]

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.
