Well with the new Mach 4's installed truck runs better less smoke and less heat than mach 3's. Don sure has kept improving injectors over the years, my 3's were 4 years old. The old injectors worked perfect i just heard good things about the 4's and thought i needed them. Cant wait to dyno again and see how much i improve over the last 451hp and 1024ft lbs of tq. Thanks a lot to Rip at Source Automotive he is a real nice guy and shipping was fast.

 

No wonder nobody buys the 3's anymore- less smoke, less heat, and more power with the 4's for the same price Can you peg your pyro guage pretty easily? Does your butt dyno feel the difference?

 

What HP are the Mach-3's rated at?

 

3's = 130 HP

 

I found the same results when I upgraded from the 3s to the new 4s. Less smoke, less heat and a better ET but I haven't gotten recent dyno numbers yet.

 

SWEET!!! I'm lookin to put some Mach 4's in my truck here soon so that is great to know!!!
