OK, I am thinking about upgrading again... ... ... ... .
I need to know who has the Mach 3's and do you like them over any of the other injectors? Also where to go to buy them, ya I have not been following all the info, and can't get a search going looking for Mach 3's.
Are they going to be a better kick in the butt than my DD2s? Can I tow 8000lbs with the box off with them? Just a few questions, not too bad. Thanks guys... ... ... ... ... ... ... .
