DP 80 ECO VS 80 tow

Hey guys love my tune first off. But should my 80Hp Eco be a ton stronger than the 80Hp tow? Mine is if i keep the gas the same and switch the 80Hp Eco is a ton stronger than the tow? Is this right? And my 120 race feels the same as my 80Hp Eco?

Thank you Skydog

yea my 80e tune is stronger than my 80tow, but not way stronger.

the 120 should be noticeable stronger than your 80e tune.

Probably just differing power at differing RPMs. Only way to find out it the E is stronger than the T is to put it on a dyno or run it down a track.

Or ask Jody.

Your 120 could be the result of an HPOP that isn't functioning well at higher RPMs.

My 120 is much stronger than the 80 econ tune. I can really tell a difference when I switch from 80 to 120. However, with my stock injectors, turbo, and HPOP, the 120 race is stronger than the 140 aggressive. But....the 140 blows a lot more smoke.

first, you're not really supposed to be switching programs while under power, or while moving at all for that matter. but do what you want, i'm never on any roads in IL.

second... when i ordered my chip, jody's other employee guy (can't remember his name) told me that since i had the 6spd, the 80e and 80t were the same program since they differed only in tranny tuning. however, from what i've read lately, it seems that maybe tow has more power at lower RPM. If this is the case, i wish i had gotten the 80 "tow" instead of 80 "econo"....but maybe 80 "econo" works better for MPG and daily driving. maybe diane can chime in?

When I asked Jody about switching on the fly he told me that he had guys that switched his chips two or three times just during one pull (tractor pulls). Switching while under power and moving is fully condoned by Jody.

80tow and 80econo are different. On their website it has a specific weight range the 80tow is recomended for and the 80econo is recomended for driving around empty and max MPG.

I also understood that you are not supposed to switch when under power when I bought my F5. My econo tune is a good one and with the few other mods that I have done, if I can tolerate to drive at a reasonable speed on the interstate I have gotten upwards of 20+ mpg not by my fuel guage but by doing the math so I am impressed
