You wont be disappointed 
Let me know how it goes though Im curious how well the turbo you have will work with towing that load with those tunes. If I was a little more tech savvy I would learn how to data log on my dash daq.

so when I go to load my custom tunes and the adjustment screen comes up on my X4 what settings should/can I mess with? I assume tire revs and gear ratio are a must but what about rev limiter and shift firmness % and "firmer shifts"? are these settings already done by the tune writer? he set my WOT shifts at 3800 rpm, do I set my rev limit to 3800? seems I should because it comes up as 3600 rpm default on the SCT...kinda confused and forgot to ask when I had them on the phone.

Same here, except I did turn off the speed limiter. I'm not certain any of those settings have any effect on the custom tunes though.

Been running the custom tunes from Matt a week now. SLR+ seems to shift to the next gear pretty fast, looks like it's trying to keep me at 2500rpm. Spins the tires easy in 1st thru 3rd and a big puff of smoke when you nail it. Not sure I like the smoke, you can tell I got in the throttle, like a warning. Not sure if staying in gear a little longer wouldn't hurt, probably call and ask.
I can tell my mileage is up, almost 200 miles on 1/2 tank, that's about 50 more than normal. Turbo lag is down, power is increadable in 5th or 6th gear with no lag. I pass cars easily at highway speed and it hardly ever unlocks the converter. It locks up fast and stays locked.
Im loading the SLR XX probably Sunday so see what's changed from SLR+. Going to try tow/haul mode to see if it will hold the gear just a little more.
