I just did the TH fix about 2wks ago & I couldn't be happier. My car never moosed so I didn't concern myself with that, but the TH made the car very irritating to drive at times. Now it's sooooo much nicer & the "power loss" is probably a bunch of crapola as I haven't noticed any whatsoever. I mean hell for $.50 or less (free in my case as I found a pipe cap here & borrowed the drill bit) and maybe 5min worth of work it's absolutely worth trying & it's easily reversible so no worries there either.
