I dropped in a K&N filter and cleaned up some obstructions in the air box a few weeks ago and was pleasantly surprised with a little better acceleration and passing. Looking for some additional intake improvements, I decided to optimize the throttle body and was really happy with the results! Throttle response is considerably improved and the car just pulls and pulls up to red line! Here's some pics of the before and after results:

I'm curious what the dyno results would show? I got about 5HP on my old 2.3L Mazda, but this feels like a bigger difference all the way around...

Nice work, I purchased a larger T-body to replace the OEM one and if it hasn't been modded where the butterfly opens all the way, I will go ahead and fix it.

Thanks
