hi sir, i live in Bacolod City, i'm very interested with racechip, is it ok if i just buy a racechip from you and just plug and play it to my GLS-V? what's the advantage of dyno-ing it on my (customer) side? it's just if it's a must to dyno my ride, i have to take it all the way up to manila from Bacolod....please give me advice on this, thanks!
