Adding an inch of length to the throttle body area doesn't create horsepower and any mechanic who knows a little about physics will explain this too you;your ponies are coming from the CAI.
My friend dynoed his '02 Tacoma with a K&N and deckplate mod and he netted between 5-10whp on three separate pulls and on another accasion he threw on a TBS just to prove a point and there were no consistent gains and netted the same horsepower with just the deckplate mod and filter and cost a total of $52 ($40 was the K&N) for proven horspwer and isn't that cheaper than the TBS by itself?
I'm going to get a dyno reading for chuckles and grins this spring and I'll do runs with the deckplate in and removed to see what gains I'm getting.
