Sorry guys im coming from hp tuners for ls cars so bare with me.

Can you use the plug and play units if you have a cold air intake and ported tb??

On the plug and play units under normal driving do you guys see same or better gas mileage?

The piggyback boxes for the Abarth will hurt your fuel economy, on the order of 2-3 mpg. They all increase boost but have no control over timing or a/f mixture. So the ECU compensates by throwing more fuel into the mix.

I used HP-Tuners on my STS turboed '04 GTO and on my '02 Z06. I really wish I had that level of control over the Abarth, there are so many parameters that need tweaking on this car to improve performance and driveability.

But man does it add a lot of fun along with the added need for gas! :D Guess till a real tune solution hits the market might as well enjoy the added fun.

I run a TMC unit on the highest level (9) and a RRM intake by the way.

^^ this. the piggybacks are far from ideal, but they work well enough.

no issues at all with my mm box and atm intake paired together. car feels strong. a real tune would only help.
