Yeah I am skeptical, but have volunteered for the testing, I do not know much about how it will all work and will just be reporting any/all differences in the way my car drives and feels.
Also mine is a stock R33, and that means totally stock, no body kit, no filter/pod, no exhaust, rock stock, so might not see much difference, but I will be objective.
Have alread started preparing the report, noting any/all documentation and "promises" or "results" this product's promotional material tells us it "will" do and use that as a benchmark for my results.
I'll keep you all posted.
For those blatently calling this product "magic beans" all you are doing is basing your blather on heresay and not on factual results, hopefully which the people doing this testing, will be able to provide you all with to either prove or disprove what this product actually does.
