I just find it funny how a bunch of people cry about "skewed" info, etc., If the a/f is closer to ideal, I dont see a problem, its cheaper than a dyno tune and really isn't a chip just skewing the info also??
to each their own, but evn if the power comes from better a/f ratio, I dont see any problem w/that, if its making more power, better a/f ratio(tuned better), why is it a problem?
I came from the world of 5.0's where chips never really got any respect, maybe thats why I cant really see the expense of dyno tune being worth while on a stock motor, I guess if you figure cost of speed cal+timing adjuster, your half way there and raising the rev limiter is an added bonus
I recently descreened and deposted my stock meter w/excellent results, I'm actaully still surprised at the difference. Thats why I was curious of the size of the sampling tube, but I researched and a ton of people have done this, only 2or3people on the internet preach against aftermarket maf's, mostly Ed Clark and phatdoggy, several others have chimed in w/good results, many reporting .1 and 1mph(10hp), enough to outweigh the 2 oppinions I tink
why the heck would you want a stock n/a motor to have a <11:1 a/f??
I dont believe detonation is detrimental on n/a motor, at least not at this rpm/hp level
Sorry, didn't know I was in the presence of the god of drag racing.
