hey im in the same spot as this guy i have a long drive to school everyday and would love to get an extra 5 mpg. is there anyway i can get the details on what yall did. see im gunna be buying a dsp in less then a month. and is there a limit to the mods you canhave to mantain half decent mpg?
When you get your DSP we can set up you with a MPG tune that you can flash for your daily commute.
Give us a shoot as well when you buy the DSP, we have them set at a low $375 with cable kit and free plugs (2 step cooler units) through the month of Sept. That is a killer deal!

that will be awesome , thanks ill for sure give yall a call when i get it
Buyer beware:
I would be extremely surprised if a meaningfull mpg improvement could be realized without significantly limiting drivibility or risking engine damage.
The PCM and the CMR software is very limiting in the options available to increase MPG. The most significant way to increase MPG would be to run open loop the whole time by deactivating the upstream O2 sensor and then sevearly manipulate the VE and P-ratio tables to force the A/F leaner. While this course of action is available, it would be reckless to make such a significant change to the opperating A/F especially via an email guess and check.
Any other bs "MPG tune" that would still use the O2 feedback for closed loop would not see a meaningful change to MPG and would be a poor value if you paid more than $5 for it.

We do none of that, we just kill the WGA duty cycle and mess with the PT throttle timing and WOT timing tables (and some other things). We also drop the redline down to 5200 RPM, this "MPG tune" has been proven on a few locals cars and we have a few others running it for testing purposes and the 5MPG gains are not uncommon.
Duster, why would you state something like this? Why do you keep on giving "warning" or "buyer beware" to our tunes? Maybe he is going to get the tune for free, would it be a bargain then? Seriously.

That "tune", as you call it, will do no better to increase mpg than what anyone can do with a disciplined right foot. I seriously doubt you'd disclose that fact before handing them the bill. Free is about the right price. Charging any amount of money for it would be unscrupulous. If I keep mouth shut, I'm sure I'd see a "PTP MPG TUNE SALE!! $50" thread next week.
My problem with this other PTP products and service is that PTP walking a fine line between offering marginal products and flat out taking advantage of misinformed consumers. This "MPG tune", if sold, is a flat out rip off plain and simple and PTP knows it.

Maybe people don't have a disciplined right foot and are willing to pay for it? How about you let the people decide instead of deciding for them, thanks.
my so called MPG tune was $30 and havent been able to prove it works, im still in process. i just picked up my o2 sensor to replace and see if it makes a difference. but todate i dont think its working, and i will get with my local tuner and discuss why i dont think its working after a few more road tests.
on a side note the stage 1 does it completely ignore the downstream sensor for open and closed loop? i dont have it screwed in my down pipe, i am thinking of connect it back on also see what happens.

hey thanks for the heads up its nice seeing people care about random strangers.
but i am willing to try anything to help with the gas mileage. and i have to get a dsp anyways so i dont see the harm in atleast trying. this is gunna sound really snobish but its money. if i didnt spend it on m,y car it would end up as food. atleast this way id be able to sleep better at night knowing i atleast tried and thats to say it doesnt work. maybe it will and ill get the full 5 mpg's and ill be one happy guy

hey man its cool, I still want the tune and what not. I mean i understand there are companies out there that will screw people over and that kinda thing but they dont tend to last let alone do you here people saying there still buying there stuff. I have full convidense in you guys

Thats EXACTLY what I mean when I said you're "flat out taking advantage of misinformed consumers."
So you're saying its not your fault if guys are stupid enough buy it?
