I usually don't like to write a review, but Gernby etune is one of the best mod for 06+ S2000
If you own a 2006+ S2000 NA setup and have a Flashpro, highly recommended to get a custom etune done by Gernby.

Car setup:
2008 S2000 CR
FD 4.77 KIA Gear <-- Yellow Jacket set at 31%
Comptech Icebox Intake
Toda Standard header
70mm TP
Toda dual dolphin exhaust

Here are the Review:
When I first loaded Hondata Toda tune map in Flashpro, I feel hug torque and hp differences than stock map. But, I notice I'm getting few numbers of knocking on every cylinders during low rpms.
Long story short I reached out to Gernby, he provided me with series of calibrations and easy step by step guideline to follow, I was very impressed with his unique tuning. End result, final STD map is freaking awesome~! it's not just safe to run without any cylinders knocking and car pulls a lot harder than toda tune map. Highly recommended and thumbs up for his service.

5/3/2017:
Version 2 final STD map from Gernby is freaking awesome, more torque and hp compare with previous STD from butt dyno.
Test result with neighbor 2017 Focus RS with mods (Cat back, DP, Intake, catch can, cobb stage 2 map) <--- runs very rich
From 0-73MPH same acceleration, RS starts pulling away after 80mph..

You need a high flow cat (or cat-delete) to fully benefit from a 3600 rpm VTEC. OEM exhaust is heavy and boring. Berk 63mm HFC and Tanabe Medalion Touring were my choices. Gernby tuned afterwards.

I know the Gernby tune does wonders but that rs with those mods should destroy you especially from a dig....

Sorry to be off topic but I was thinking the same thing. What is wrong with that guys RS? Or did you mean ST?
