Are you sure that your mates is stock standard?

Maybe your testing equipment isn't as accurate as his????

Hey Craig,

Was he stalling it on brake before take off? When he didn’t stall we were getting as high as 7.9 seconds.

Btw, he had his tune done on Monday. Had a quick chat to him last night and he is very happy with results, especially roll on acceleration. He re-run a couple 0-100kph and is getting 7 seconds flat, couldn’t break into 6s.

Thanks,

Ben

Hey Ben,
Most before and after figures are on The Horsepower Factory website.

You are right Ben. I could only see figures for the SRT.

Give them a call and ask for Matt (Trailhawk) and he should be able to tell you.

The 8.7 sec to 100 kmh for the 5.7 hemi is for models 2011-2013 (different transmission - 545rfe or 65rfe).

From 2014 the 5.7 hemi has an 8 speed and I believe the times stated are 6.6 sec to 100kmh.
