Howdy, I just bought the CAPA flash from sportcompact.biz off of ebay. I have to say the service was awesome, I got it within two days, it didnt work for some reason so I called them and they sent a replacement the next day. top stuff Obvoisly this one works. I just have a few questions. I installed the 98 octane tune that came pre-installed in the box. Faaaaaaark did it make a difference. Is it normal for the boost to really kick in from about 4000 revs or should it be smooth through the whole rev range like the standard tune. I'm serious, the boost like kicks you in the guts. and....how can you tell if it's running rich. apart from the boost really kicking in it all sounds normal.
