Gtech or Racelogic Power measurement tool

Hi guys

Want to know what do you guys think about different power measurements tool?

I don't have dyno for my test so I use PerfExpert.

It's not so bad and give me 80% of the time correct results

I see some portative power measurement tool like G-Tech or Racelogic

Have you guys test or have some feedback about these device?

i have bouut device gtec not good
looks for insoric

Thanks for the reply mate have you ever try in sonic what's your feedback?

insoric once setup correctly can give good repeatable results, its one of best tools you can get without buying actual dyno
