Well I just did my first official Highway mpg run, about 20 miles. I averaged 18.1 mpg at an average speed of 70mph. I cannot believe that the fuel mileage increase was so much. I was only getting 14-15 before. As for around town I have only seen a .5 mpg gain. Mainly because I love the way it sounds and it is hard to keep my foot out of it. I need to try one complete tank of gas and keep my foot out of it and see what I can get. Anyway I'll take the 3-4 mpg gain on the higway any day.

 

Wow... I do believe we have a winner. One of these things coupled with a ramair box might actually put a 5.9 into the 20mpg range.

Deffinetly deffinetly getting one...

 

That is impressive.

 

what can you say about the power? i've heard you loose your low end torque, and driveablitily with that intake. congrats on the purchase

 

nah with the hughes you shouln't lose low end. Its made for that. You lose low end with the M1 though so I have heard

 

good deal. i was gonna get one, but i held off because of i heard its made for high rpm. "pdavis53", is the performance gain noticeable. it better be for six hunbo. lol.

 

I would do this mod again, again, agian and again. No I do not loose any low end torque. It definetly has a noticeably increase in power. As I have stated before it is like having another gear once it hit's 2500 rpm's. The truck does not shift as much either and I think that is the biggest reason for the mpg gain. As for driveability It is a daily driver and I mean like 100 plus miles a day and I have absoultely no problems with the drivability of the manifold. Hughes really did there homework and made a very good piece. Remember that this piece was made specifically for this engine therefore everything has been addressed. Again I would do this mod again. I am really happy with this mod, to me it was worht every cent.

 

I'm thinking reeeaaallllll hard about getting this intake. How about an update, with 2 more months gone by? Driveability, mileage, whatever you have noticed. It sounds geat, but 600 bucks is an awful lot of money.
Thanks, Gas.

 

At the rate gas prices are going I would take one. Espicaly with a 3" lift more suspensoin in the wind now.

 

great another thread to make me want it more , cut it out i get the point lol good to hear your happy with it , keep us updated , did it change the sound of your exhaust
