I have 07 tiburon v6 and it feels like dont have enough power like it suppose to the rpms kinda go to fast when I accelerate how can I fix that how can I bring back the power

If the engine speed revs too high and you don't have enough power, it sounds like the transmission is not shifting as needed into the next gear -- assuming automatic transmission. If manual transmission, it sounds like a slipping clutch. Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops
