If anything those G-force adapters would only make the car run unsafely. Luckily in this day and age most popular applications we dont have to utilize "piggy-back" systems to tune vehicles. Going through the factory ECU will provide the best results on a street car. Standalone EMS systems are great but can take some significant tuning time to get everything dialed in to behave like a factory ECU would.
UpRev all the way!
