Yes and I used 93 octane at sea level. You can also change your program by contacting Nelson, as TAZ has recommended him often and is an expert at that stuff.

Bet it makes you smile when it wines. that will improve your throttle response 100% . most times a good dose of $$$$ can improve anything. they should have had a SC from the factory .

I changed the pulley on my mag charger and brought it up to 8lbs of boost. So far so good with my mag, truck runs as reliably as stock but with tons more power. BTW, I don't find that the mag charger wines very much at all, if it wasn't for the power I don't know if I would know it was there at all.

Yea, doesnt whine that much, but under hard accelleration it makes a electric golf cart whine.

There really is no maintnance, I called mag and they dont recomend changing the oil till 100,000 miles. I checked the oil in mine anyways and it was fresh out of the bottle clean (And thats after 30K miles)...

Just installed my magnacharger this past friday night. All I can say is, WOW! I did happen to take video of my SUT going 0-60mph before the upgrade. I will get a new video now that everything is installed and post them both to my web site. I also have a couple condenser mics and will soon get a good quality audio recording of the new magnaflow exhaust combined with under-the-hood sound, such as the magnacharger winding up.

Any of you guys having tranny problems? I've read several people that have blown trannys due to superchargers.
