Ok, so we did everything we were suppose to do and waited to few days for the Truck to reset it's self, we decided to go back out to the same spot, that we did our test runs at, so with my SantaFe 2.7, with Moble 1, K&N oem replacement drop in filter, also KDM strut bar, and my buddys truck with all the same but the intake mod, with a cone style air filter and resonator box removed and plugged so the air would flow better, so we lined them up, and off we went, on the first run we took off at the same time, and we were side by side when I hit third I looked over and he started to pull away from me now I was looking at his side passanger window, that race he won, but only be 3 feet, so we did another run, and that race was even, we did about 7 runs that day, and he won some and I won some or they were still even, but the run's that he won he only beat me my 2 or 3 feet with the intake mod, I guess it was who ever got a better jump off the line, but he's going to leave it like that for a while to see if it will only get better or till the Hyundai Dealer say's something, well let me know what you think.
