I have talked to speedtuning as well, ask him what the redline is after the remap. Also does his remap do away with the top speed limiter? He told me I SHOULD also install K&N's as well in order to really FEEL the difference. I don't want them and told him so, and he was reluctant to give me any HARD data. He acted like he didn't want to do the remap without the filters. I suspect he's over doing it on the numbers.
