Question about custom tunes
I just emailed my order form, with the stock 87 tow/custom 87 perf/custom 93 perf
My truck is an 04 FX4 (non-heritage) and I'm just wondering if these were the best tunes to go with. I have K&N CAI, Flowmaster SI/DO, and troyer pullies. I do city-highway mixed driving, with somewhat of a lead foot. Any input would be appreciated. I wont even be able to send them my hex code for about 3 weeks, since I'm still in Iraq, so I guess there's still time to edit my order if needed.
