Speedo

[Masterelec2018]

Probably not the right sub forum to post this. With the upgrades that I've done I have found my speedo to be way off at higher speeds. Went from 245s and 3.42 to 3.73 and 265s. What's the easiest way to fix this. I do have a Bluetooth ob2 adapter. And I do plan on doing a trnas and ECU swap when I put the 5.7 and 4l80 in. Should I just deal with it till then or is there a good program to use on my phone/pc to tune and change it

Deal with it when you do the engine/trans swap. The trans will also have different gears and you’d have to tune it again anyways.

Use a GPS speedo until then.

Use a GPS speedo until then.

Or a Radar Detector that tells you how fast your going.
