I bet she pulls way harder from a dig tho

[601Jcoop420]

It's hard to judge the difference seeing as the speedo is off with the gear set... ( I swapped 342's for 4.11.. made my speedo look way fast till I got the speedo calibrated) get those shift points taken care of and she'll open up a bit more

If you recalibrated your speedo for the new gear, your mph would be less at the shift point. But it looks the same
