like i stated before, i have used SMC, Devils and Razzors systems on differnt cars in my area. Tunned them all on the dyno with a wide band and direct scan
Bottem line -----THEY ALL WORKed flawless " and i didint need to call anybody"
I've ran an old Bowling Green Customs alky kit way back when almost no one was running alky and most guys where acting like I was messing around with voodoo magic or something. I had good luck with it but it wasn't very fancy nor was it very expensive either.
I then went to one of SMC's original kits and was very impressed with ease of use and tunability. These are awesome kits for about 98% of the guys out there. Steve has made improvements to his kits over the years to make them even nicer. Anyone who I helped straighten out the tunning of an SMC kit all made the same two mistakes.
1. they had the alky kicking on too soon
2. they where trying to spray way to much alky and where bogging the motor
Make a partial pass on a back road, read your scan tool, make a quick turn on the two knobs, done! With a scan master, translator plus and extender chip, smc alky, and a cockpit mounted bleeder vavle for boost control you can set the boost, fuel, and alky and have it all dialed in in about 15 minutes total. I have exp with SMC kits that didn't have this set up and they where very easy to tune also, but the above set up is my favorite combonation. It works VERY well over a broad HP/performance range.
I like the concept of a progressive kit. I don't think the progressive kits will really shine unless they are in the hands of some one who's trying to get pretty aggressive with alky. Alot of guys running the PAC kits are not trying to max out. They are still very happy with them so you don't have to be a hardcore guy to appreciate the kits. My buddy Surej ran a PAC kit and he really liked it.
Steve at SMC is now making a progressive kit. These new kits seam to be just a nice as the old ones but also include the progressive feature. We have one of these kits on a buddies car and it seams to be working very nicely and is reasonably priced as well.
With PAC and SMC you have two nice progressive alky kits on the market.
