Actually I withdraw my statement regarding Trial because I didn't end up going there not because of the tuning but what an employee did. I was referred to William by a credible source and based on my discussion with him, I have absolutely no doubt that he is capable of delivering what he believes is possible given my mods, ECU and rest of setup. Basically, he knows what he's talking about.
But I guess different tuners have different approaches. Some are conservative while some tune for high HP. But sometimes customers want to have high HP, pushing everything to the maximum. Some would like to have the comfort of knowing that they are producing power well within the limits of their supporting mods.
Importing Japanese tuners isn't something new; even in Malaysia. My friend used to have Koyama tune his car and a few friends but this was in HK. But one thing about some Jap tuners is their approach to road tuning especially at high/top speed. Because road tuning in Malaysia I believe improves the overall driveability but how many are going to tune at very high speeds?
And whoever says that 'dynos go up to xxx km/h' consider the fact that just the amount of air flowing at top speed alone cannot be replicated on a dyno.
