Hello. I just got a 2018 Fiat pop and am looking at some upgrades. I've already ordered a gopedal and am thinking of a ECU piggyback unit.

The first one I'm looking at is the madness model.


I'm unsure about this one. The 2018 pop has an identical drivetrain to the 2018 500 abarth. This ECU tunes to abarth level horsepower. That seems a bit underwhelming because there are Abarth ECUs that tune around 190HP.

The second ECU is by Road Race.


It is more expensive. But, looks like too much of a good thing without seeing what current owners think. I doubt that it would actually test at 250 HP. If it did, would the Abarth class drivetrain take that sort of stress?
