from my friend experience, robyn is a so so tuner..but i dont like the way he treats his customers..like there are a dozen of customers awaiting for their cars to be tuned. 1 question, 1 answer. according to my friend, after installing new extractor, changed from drop-in to open-pod air filter, performance spark plug, install voltage stabilizer, change engine oil to fully synthetic and even using ron97..he managed to increase only 2hp only and the susprisely, the torque decrease. the power lost is noticeable especially the torque after retuning.
robynn, i hope u read this. hehehe
