TBS- Helix VS P2R Question

miketat594 · 05-09-2008, 02:53 PM

Anybody using the Helix and how does it compare to the TBS from P2R any Pro's/Con's on eigther of them, or any info that may be helpful. I use my 07 si as a daily commuter 140 miles a day round trip, and from what I see they all claim to get better milage. Minor mods include SRI, AXLE BACK and UNDERDRIVE PULLYS, I would love to do more to the motor but for now I need to keep it reliable and want to maintain the power. I already know that TB spacer's are not a big power gain but do they really have any advantage as far as milage is affected?

been looking at both of these, and still havent found any dyno results on the Helix that would put it over the P2R. Subscribed
