I WILL NEVER, and i mean NEVER will buy an ignition box made by summit racing. dont get me wrong, i like there service, products, and cheap prices, but there ignition box sucks. i put it on my car and it ran like crap, took it off, and it runs like a champ. anybody else have any problems with the summit brand?

Their 58mm TB for my LT1 didn't shut properly, which was weird. They allowed me to return it for a full refund though. I don't plan on buying too many important pieces that are Summit brand any longer but that's just me.

I use Summit as my parts supplier usually, unless I am buying from people on the forums.
