  1. Whipple build going into limp mode

    SRT Hellcat Performance
    2015 hellcat charger mmx 411 stroker with whipple 4.5l blower. Right after the whipple install we are getting various codes that seem to be putting the car into limp mode. According the the tuner code u11bc is the culprit however there are several other codes showing up. Just wondering if anyone...

    I wanted to update the thread. Went back to stock TCM and no CEL. We then started to build back up to full TCM tune. Next step was increased shift pressure and again no CEL. It wasnt until we loaded in the higher shift points when it became an issue again. Same spot between the 4-5 shift. I...

    We are trying a stock TCM file with the PCM tune to see if the problem goes away based on my recommendation. It may be the wrong approach but trying process of elimination at this point. We tried another file last night from a car that has not had this issue but it happened again. Same spot, 4-5...

    Thanks for the reply. I am working with the tuner so hopefully we will come up with a fix although up to this point he thinks it may be mechanical. bmeaggie, I believe it was happening between the 4-5 shift which make sense now based on what you are saying. The first time it happened is when I...

    Any updates on the bypass issue? I couldn't get a full 1/4 mile pass on Saturday. It was like clockwork. As soon as I hit the 1000ft mark the cel came on and power loss. Same code PO1620. I changed files in HP tuners, erased code, etc. Nothing changed the issue.

  19. Hooking with 900whp on the street

    SRT Hellcat Wheels and Tires
    Currently Im running MT ET street R's mounted on an 18in weld and I am having issues hooking as well. I was thinking about dropping to a 17in and going to a 315 tire. I did put the 2.62 diff back in and found that made a pretty big difference but Im still spinning through 3rd. I think a 15in...
