Anybody in the north east region going up for test and tune on Sunday? Just thought is would be cool to see a couple more SS's there. It runs from 10 - 2:00 or later depending on how many cars there is. I'll be there with the official slowest SS but it's all good(i have fun anyways). Any body going look for my plate Massachusettes "SS03". Love to meet some of you there. Look forward to seeing some of you there.

if you don't want any real problems have it professionally evacuated and recharged. when you take the switch out, the oil in the system will suck in all the humidity and create water in the ac system. this will make problems with cooling as well as corosion. you should evacuate the system for about 1 hour after opening it up to properly remove the moisture. Just be careful about what shops you go to. what i do at my shop, is i have two ac machines. one i use only for sucking down systems, the second i use for charging. reason is you never know what your actually taking out of other peoples car (sealant, r12, autozone additives for "colder ac" ect.) you don't want any of these in your system, the do more harm than good. R-134a has come down in price, there is no reason that the system shoulden't be charged with brand new (not recycled) refridgerant. Also don't check ac systems with gauges, its not accurate. air in the system will make pressure. Use temperatures of the high and low side using an infared thermometer. this will let you see what is reall in the system and how it's working. second, i have found that 90 percent of chevy and gmc trucks come factory filled about 3/4 of their total capicity right out of the factory. another problem is the design of the condensor dosen't allow enough air to be sucked through when at idle. the fan does a nice job pulling air through the radiator but not enough to pull air through the condensor. E fans help big time with this. hope this info helps.

i thought he was refering to the firestone universal kits. a lot of fabrication is required to put these on. my mistake.

great tech article, i would go with the mcgaughy's bags though instead of firestone. they work great for towing, wouldn't even know the truck is lowered
