This post got my attention. Want to know everything about it. I am weighing getting rid of the RRM Tuner this year, getting the Syked 2.4L Tune and then getting the MPx Header/Exhaust combo after winter or getting MPx Header/Exhaust combo before winter and then getting rid of the RRM Tuner and getting the Syked 2.4L Tune next year. I do want to see how the Syked Tune is without the MPx Header since it is built to run with it.Ordered my Syked tune for my 2.4. Really looking forward to see the increase vs using the spectrum Tuner.
