    Thumbs up PTF 91/E50 Quick Review

    When ATP was released and PTF decided to do a group buy, that's when I decided to jump ship from GIAC. It took this long because along the way, I had some problems as listed below:


    1. Deviation between the two AFR banks. The BMS DP Fix set at the lowest did not disable or fix the deviation. Removing it completely was the solution.
    2. Wastegate rattle. Had to remove DPs and dealer it. The only thing they did was adjust the wastegates but there is no longer a rattle.
    3. Boost leak. I went ahead and got an ER chargepipe. I'm not sure if this fixed the problem as I installed it right after the rattle got fixed.
    4. When on the base E50 map, clutch started slipping. Got an HPF S2 clutch and used an OEM DMF. After 500 miles, the tuning resumed and the results are below.

    Right on bro!
    Nice results!

    Are you going to make it to Sac RaceWay tonight? Kevin @ MCE Racing with his 224 DynoJet will be there. I can't make I am in Washington till Thursday.

    @lulz_m3

    I have the same problem with VD. I think it reads the Boost abs. So if you subtract 14.xx , can't remember the exact, that wil read boost psi.

    Its probably getting confused with the column names in the Cobb CSV files since so many have the term boost in the title.

    You're probably right. I was just worried about possible fuel system damage with too much ethanol. How long have you been running E50? Thanks!

    I'm working with Jake right now to finalize an e50 w/93 map. So far this thing rips!

    PTF is the way to go! =)

    Personally I have been running it for a month now so I can tell from experience that nothing will happen. However I have a couple of local friends who run E85 for DD and have been doing that for much longer. They saw no issues yet. The only issue I'm seeing is my LPFP is not able to keep up. It's not at a point where I'm leaning out but you can see from logs that LPFP is on the verge.

    Don't get me wrong, my LPFP is relatively new and it's not weak by any means. As in even if I swap it for a new one, i'll get the same thing. WE need an aftermarket pump or an inline pump...

    I say go for it and don;t think twice. It is worth it

    You can also log "boost" on your AP if you want VD to show the relative boost
