    After I got my lower intake ported, I started hearing a lot more cracklin from my exhaust. Like back pressure popping. Not backfiring. Is this normal? Another thing is that while in 2nd gear and driving steadily at 3k rpm, my car misses and kind of bogs a bit. Any idea why? It still tears the tires up if I floor it tho. My f/p is at 40psi and my timing is set @ 15* with 93 octane.

    The bucking and kicking at cruise is the stock computer not know what the hell to do with all the mods you've thrown at it. Mine does it from time to time if I "lug" it down low. As for the cackle, I wouldn't sweat it. Major mods will change your exhaust note. Think about it....a H/C/I car with the same offroad pipe and flows as everyone and their mother sounds totally different. At least mine did.

    Yeah, I'm not too worried about it, I just needed some reassurance. I checked my plugs and the mixture seem perfect. I'll be bumping up the f/p another lb or so just to make sure it's not leaning out over 3k. Thank Ryclef
