[QUOTE="nuacr0s, post: 15544670, member: 175931"] The other possibility for the hesitation under boost after shifting gears could be carbon build up. I know my Roush has only 12k miles on it, but it has been some serious combustion issues recently that even caused of my O2 sensors to go bad. I'm wondering if that also caused carbon to build up inside the upper engine areas, even though I run pure, non ethanol 98 octane gas. Has anyone ever used the infamous Seafoam product? is it possible to do it safely in the SC car? do you have any pictures of where and how you poured/sprayed it in? I am thinking of doing this tomorrow, before I replace my old spark plugs and change oil/filter. Thoughts? [/QUOTE]
