Engine/Transmission (1998.5 - 2002) Which is best for MPG- EZ,Mach2's, or EZ&Mach2's

[MDale]

Which combo is everyone getting the best mileage with? Just an EZ, just Injectors, or both? I was getting 19-19. 5MPG with just the EZ, then I put the injectors in hoping for about the same mileage but have droped to 18Mpg that's with the same driving style as before the injectors( get on it once in awhile, It was hard to go a week without stomping on it ). I've also ran the Mach 2's with the EZ on level 3 &now 1 and still 18 Mpg. Just wondering if this is what everyone else is getting with this combo.



Thanks,

Matt

On my truck I was getting close to 19 on the highway with just the EZ Then I put the stage 5 jammer nozzles and the edge comp box in and on the highway I have no prob getting over 20mpg just depends how fast u drive - at 65 I've gotten 21. 4 and at 55 I have gotten 25. 8 and that is with no horseplay.

Roughly how many miles are you getting out of a tankful? My 01 ETH is giving me roughly 400 off of a very full tank, mostly highway and country driving, without a load. Usually around 350 with. I believe the shortbed tank holds 30? Thanks

btw what kind of egts do you see towing w/ the ez and 2s? I tow heavy on a pretty heavy basis and can keep it under 1200 pretty easily w/ just the ez & bhaf.

Thanks

EZ and Mach 4s should give you 20+

redfuelrules, that's pretty low miles per tank. If I run mine down to E, I can get 500 miles; more if it's all highway. I've never put more than 26 gallons in to fill it up. With a 34 gallon tank I still have 8 gallons left. 34 is the SB. 35 for the LB. I do have 3. 55, 2wd, and 6 speed.

My '01 HO wasn't very happy with the EZ and DD2 injectors, it acted like it had too much timing. Maybe that's the problem. It ran a lot better with the van Aaken box and the Diablo Puck.

MDALE,



Are you hand calculating your milage? I have the same size tires on my truck, same gears, ect. I usually only get 15-15. 5 all hiway. I use to have a banks fuel box on it. The computer would show 19mpg at 80mph when it was really closer to 13mpg. Stock, I usually go 370 miles before low fuel light comes on with a 34 gallon tank.





Does an EZ really make a good difference when it comes to fuel milage???

If so I want one.

With the Van Aaken and RV275's, and Comp box with Mach 1. 5s, I always get 19. 5 city/hills. SB tank has 34 gallons, and I have been over 600 miles on a few tanks (lot more highway miles).

I normally run the comp box on 1x1 for smoke control though. So I should get good mileage from that part.

And I OFTEN drive spirited, and my drive to work is constantly up and down hills (one is a 14% grade).

My wife driving gets about 21 mpg for her normal commute.

 

[MDale]

Yes I hand calculate my mileage, I get 18-19mpg and the trip computer shows 21-22Mpg. I usally get 430-460miles per a tank, and put in 24-26 gallons. I drive 75% highway miles. I guess I'll keep watching my mileage and see what happens, maybe I just like my new power to much. As for EGT's I havn't towed anything with the injectors (afraid the clutch won't hold) but racing with the mach2's and EZ 900f max post turbo. Also does a Comp have the same or less timing, and what are some good boxes with less timing, or how can you tell if you have to much timing? Thanks

Before my gear vendors I got 17 in the city 18 if I played really nice, now I get 18 to 19 normal heavy foot and 20+ if I am on highway 1800@ 78mph.
