If it sounds too go to be true then it probably is. I tried one of these on my last car (elantra gt) because professional tuning wasn't available and I knew better but figured what the hell. It did nothing except make my throttle response jerky. Not better just jerky. If there was 60hp available then pro Tuners would have already found it for our platform. If you want to wake up a stock gt just tune for e85. Best bang for the buck.OK OK.... I got it
This. By a mile.If you want to wake up a stock gt just tune for e85. Best bang for the buck.
