It only had a Herrod twin exhaust and tune when it ran this, but since have had the cat punched and a K&N added with a boost reduction. Difference is? Im no dyno king so dont really know the difference and he also runs a lot of turbos on it, and is pretty comparable to a couple other dynos in Adelaide. Anyways been thinking about getting run up on street tunas mainline, as a few have said HPT's read a little high, no bickie really, thinking about it now I probably should of waited to post it in here until I had smashed it. Hey its a learning experience, As Ive said in my FPV thread its just a number and am looking for a whole lot more in the long run so we'll see where it goes from here.
