Fooling a decent oem tune to make more power on a better built engine is different than fooling a not so decent oem tune to make more power on a much more fragile cheaper made engine. The latter will have more issues every time. Neither one will make as much power, be as safe, or have some features an ecu tune can have. And all can be detected unlike some may claim. By the time you get a piggyback to do all it can do and still not add up to an ecu tune it will also cost more.I am planning on going with a JB4 for my ‘16 VT. I’ll let you know if my car blows up.

Burger motorsports has been doing this for a long time and people with a lot more powerful and valuable cars have had great success with them.
Piggyback tuners have come a long way and they aren’t all like the old-school ones that just do stuff like fake the intake temps, etc. No method of messing with the ECU is guaranteed safe though. I like the JB4 because it connects to the CAN and reads several systems to try to make sure it’s not running too hot, etc.
That's a pretty reasonable goal. I estimate I am at that or higher with my mods, some ethanol (side note, trying alternate ethanol blends is not recommended unless someone knows what they are doing), and stock tune. I have reduced weight to make it quicker too. I have a similar approach with my VT. Most of my experience has been with NA cars and the VT was just to have something zippy for a long commute. I work remote now so I am looking at getting a bit more adventurous with it since it can sit for several days if I do a bigger project.Crank, 70hp over stock 201.
