    So I picked up the DashHawk and I have been testing out the performance tests on it. The available tests are 0-60 and 1/4 mile. There is also a function to estimate the HP.

    Here's the specifics...2007 Tacoma Double Cab, Prerunner, 4.0, Automatic, LSD with premium gas. It is stock.

    I go to the track where I can pretty consistently pull in 0-60 time of 6.85 seconds. I was expecting times more along 7.6. Then I read that the Prerunner automatic is one of the faster accelerating of all the Tacomas.

    I plan on doing some more tests and getting some good mileage numbers. Because I will be installing the URD TCAI and MAF Calibrator. Although many people have done these performance mods, I have yet seen any real data on the performance/fuel efficiency gains.

    So, I don't drive my Tacoma often and I have not had many opportunities to check the mileage. Driving pretty much just in the city and with a fairly heavy foot, I was able to get a mileage of 14.75 mpg. I don't think that I can drive any less aggressively, so when I get my intake installed, I should get a fairly accurate comparative reading on the mpg. Tomorrow I might go ahead and install the intake.

    You will get better gas mileage as the engine "breaks in" , and with a little restrain of the heavy foot it's possible to increase up to 5 mpg, good luck with the install. :D

    I'm not too worried about better mileage. I still only fill up every few weeks. My truck has about 7000 miles on it now.

    So I installed just the intake today and went to the track to test it out. On the way there, I could definitely feel a bit of extra power when it hit 3000 rpm. The noise was also there.

    I was able to get from 0-60 in 6.42 seconds. On run two I got the same numbers. This is without the MAF Calibrator. I ran out of patience and I decided I better not push my luck with the successful install.

    Damn, that's almost as fast as my Altima was. Those G-Tech type devices can be inaccurate but the fact is you picked up a decent gain in acceleration, regardless.

    It is not a G-Tech type device. I think that those were more based on accelerometers. The dashhawk plugs into the OBDII port. It displays your real time stats. That being said...I still don't trust my numbers. They seem too fast.

    I have now found that I drive slower with the intake. I feel like the truck makes too much noise when I floor it and I don't like making a scene. I think I should be getting better gas mileage pretty soon. This weekend I will be installing the MAF Calibrator.

    Ah, I see. Yes, the Gtech is an accelerometer or g-force type device. I had one and didn't trust it a whole heck of a lot.

    I don't think your numbers are THAT far off. Our trucks are rated at under 7 seconds by a couple of different magazines, though I don't trust mag times much either. If there's any way that you could get to a track at some point, that would give you a better idea.

    Don't forget... those numbers are based on the mph readings that may not be 100% accurate. Take even a 1% +- difference on such a quick (small data set) calculation and you'll notice it very clearly. If your speedo is off by the semi-standard 5% you've actually got 0-57mph times. The extra 3mph might take an additional .3 seconds or so.

    I agree that you have a good comparison with your individual vehicle, but even something like tire wear over time will change your results. Good to see a clear gain though.

    So do you have the calibrator installed yet? I'm curious to see how that affects things.

    Not yet. I was going to do it yesterday but I ended up hungover instead. I just filled up since I installed the intake and so far my mpg really took a hurting. 13.5 mpg and that's almost completely stop and go traffic.

    Damn... That sucks! I only get in the 14mpg range when I go off roading for the weekend and spend some time in 4LO.

    Are you able to read all of your trucks engine parameters with the Dashhawk?

    Pretty much. The truck doesn't output all the engine parameters. If you have a specific statistic that you're looking for, I can take a look for you.

    Thanks
    I have been looking into the buying a digital gauge, but I was unable to determine compatibility of the Dashhawk. The MSD site refers to checking the OBD port to see if the 6th and 14th pins are populated. Mine are not. If yours works, it should on mine.

    I finally installed the MAF Calibrator. I'm still retraining the ECU, and then I'll do some acceleration tests.

    Got any new info yet?

    BTW, does the DashHawk give MPG info, too?
