Time for mods...

Okay so I have a 2012 F250 with the 6.2, it runs pretty good but looking for more. Truck is mainly just a DD, occasionally tows. What would you guys recommend for intake, exhaust, and a tuner? I'm thinking sct w/ 5 star tuning, who else tunes the 6.2? Also it seems the dynomax is a good performing exhaust. Let me know what you guys think.
Thanks.

Jake

I've heard good things about the 5-star tuning. I'm waiting for my warranty to expire before tuning....with the 6.2L and Torqshift being so new. If the motor or trans goes out, Ford can identify 'ghost' files to determine if a programmer was ever used.

If you are looking for a list of possible mods for your truck, check my FTE garage. I've done a few things you might be interested in.

Okay does anyone have experience with the dynomax exhaust? Or the afe stage 2 intake? I deffinatly think 5 star is the way I'll go. I think I will get 87 Econ tune, 87 performance tune, and 87 tow tune. Anybody here run these tunes?

I remember reading that the dynomax exhaust is a good quality system. However...you will loose low end torque for higher end hp.

I have all 3 of those tunes. I use the tow tune all summer while camping. Then I do switch to the economy tune during the winter, just for the better gas mileage. I do put the performance tune in once in a while when I just want to have fun, lower mpg but a lot more fun to drive. They all work great and would recommend them to anyone wanting a little more from the truck.

That has to do with the fact that dynomax increases the exhaust pipe diameter. Larger pipe gives less back pressure at high rpm's but negatively affects exhaust scavenging.

Back Pressure obviously makes the engine work harder to push out exhaust gases. So a larger exhaust decreases back pressure.

Scavenging acts like a suction on "non-continuous flow", like the exhaust of an engine at low rpm's. The smaller the diameter, the higher the flow velocities...resulting in better scavenging. Exhaust at higher rpm's acts more like a continuous flow, so it doesn't really benefit from scavenging.

The balance between these two principals is a give/take relationship.
