This thing totally wakes up the LP5, improved mileage was the reason I wanted it, power wasn’t the reason, but it definitely woke it up.
I’m going full delete, that’s why I’m selling it.
If you want extra HP, improved mileage, and something that can be installed and removed in minutes, and not traceable, this is a great addition.
