Fuel Mileage

Thanks, i had the same issues when i put my hot ecm on. I was out of air flow, i had the stage 3 turbo. I put the stage 5 on and at the same boost levels i dropped 250*F EGTs. More air= cooler exhaust temps. I push the same boost psi but the stage 5 has a bigger compressor wheel and pushes alot more volume at the same psi.

I had to baby my truck 4500 miles like you are doing now, first thing i did when i got back home is bigger turbo.

 

With the info im giving out the epa would hang me by my genitals A lot of guys dont give out their secrets, the "power world" for trucks is very hush hush, but i dont mind helping out a fellow O/O.

 

830hp You are going to need that 3406B manifold as well, it will really make a HUGE difference. I would consider one as soon as possible, they bolt right up, just gotta grind some material of the manifold where the thermostat housing is since they are so bulky.

I talked to Vic just now, the guy i bought my injectors from, and he said the 3406B manifold dropped his EGTs by close to 300*F...... I never ran the stock manifold with the injectors, i knew it would run hot, i didnt know first hand how hot and restrictive it was, but i knew it was a big enough restriction to not risk it. I mean the 3406B manifold outflows the C15/16 manifold by 600CFM!!!!!!!!!!!!

 

Alright, look on ebay, you can pick them up on there cheap.

 

6.97mpg so far

 

Thats not bad with 4.33s and that gross. I bet it will jump up once you let that beast breathe!
