I am buying the dynatech supermaxx system either today or tommarow and i have a few questions. Do i need to buy any extra hardware in addition to what comes with the package in order to have a good install? How much hp should I expect with this mod? I will have lts, y with hiflo cats, flowmaster super 40 catback, kn cai....how much hp should i expect with/without tune...i will hopefully be getting the truck tuned I jsut dont know what route i will go.

 

....anyone?

 

It would help if you update your sig. with truck specifics. You're not giving us the basics. :-)

Well, I don't think you'll need any additional hardware...my Dynatechs came with all parts necessary for installation. Regarding horsepower gains, I'm not sure what to tell you there. I think you'll feel a noticeable difference though.

 

Is there 02 sensor bungs for all four 02's on the dynatech system or just two of them, if so what 02's do you use fronts or rears?

 

It looks like there's 4 if you get the headers and y-pipe. The front O2's control fueling, rear O2's just report the health of the cats.

 

So all four of the o2 sensors are used with dynatech's?
