why not? pardon my questioning but car is currently stock... so all things equal, adding this product gave me 3% increase overall....doesnt that mean that it works? if i used a modified car, disbelievers will then say that maybe the car's timing, fuelling etc was modified inbetween runs. In my situation... nothing was touched, nothing can be adjusted cos it was a stock ECU. So isnt that's fair testing?
print out best results? would a stock car give such varying results over 20 runs? if nothing is changed....would a worst run and a best run have such huge difference?
based on what I know,...its retailing at $60 for a 1 litre can and that can treat up to 65 litres.
why not tune my car on 98 drain it then retune? would love to but my car is stock...will do it again when i have all my mods but time and money are the deciding factors...
plus.. if i did that... wouldn't people then attribute the performance increase to the tune and not the race fuel?
Although having said that, my friend has dyno graphs of R35s on normal 98 without tuning compared to tune+additive.... and the increase is even more.
But if people are already skeptical of 3% increase in a stock car... would they accept a 18.8% improvement?
