have tested somethings myself,but also have read tuning mags etc and have been told things over time by different people & tuners who have done things or have shown me things

somethings that you get told are true,somethings are completly bullshit,the thing is that you learn something new every day and that if you dont do something you wont learn by your mistakes etc
also didn't say i was right,was just giving some infomation that i have obtaine over time which i thought might be use ful to him as a guide

ps how much have you tested ?
