Once I got the unit I hooked it up, emailed back the ECU Strategy and in a couple hours my custom tunes where in my inbox for me to load onto the X4 and then into the truck. They shipped the unit the same day I purchased it.

They walked me thru the whole deal with extreme patience, considering I am a guy that can’t even program a VCR. Longer runs thru the rpm range before shifting, giving a much livelier driving experience both in the seat of the pants, and even in the sound of the engine as it winds out.Ĭhris and Josh at 5 Star could not have been more helpful. I can ‘feel’ the engine through the gas pedal. Got the performance, the economy, and the daily tow all at 87 octane (because I am cheap). Picked up the SCT 7015 X4 from the boys at 5 Star and had them load 3 custom tunes on it.

With this big 6.2L with plenty of torque and hp, why set the shift pattern up so the driver can’t enjoy or at least ‘feel’ it? Lots of lag when taking off from a start and the shift timing was horrible. No pedal feel…it’s like there was a goose down pillow between my foot and the gas pedal. It had no real get up and go off the line. The second issue was the driving experience. However, now I have come to really like it. An acre of chrome on a square nose, just did not appeal to me. Let me start by saying I really liked my truck when I first got it a few weeks ago. "5 Star Tuning gave me a whole new truck… At least that’s what it feels like. looking forward to seeing how it pulls my 15,000 pound fifth wheel next week when I go on a trip that goes over the grapevine in Los Angeles. Now it feels better than stock and I’m very very happy. My truck was never terrible but with a 6 inch lift and 37 inch tires it’s a little more sluggish compared to stock. Night and day difference from the moment I pulled out of my driveway the shifting was perfect and you could definitely feel more torque. I was just about to put it back to stock but then you guys emailed me my custom tune, so I loaded that right away…… It finally cleared and did not come back but I still did not like the shifting after driving it for a day. It shifted terrible, slipped and held gears too long and I had a check engine light (P068b) that took a couple hours trying several times to get the DTC to clear. "So when I first got the tuner from you I decided to try the street engine tune and Street transmission tune which was preloaded from SCT, just for comparison. This trip with 5star and 3 fill ups has been 7.1, 7.5 and 7.6 the last tank was highway 54 from Las Cruces NM to Tucumcari NM those of you that has driven this know of the altitude changes from 2000ft to 7000ft many times we did have the wind at our backs." Normal mileage on this trip is 6.4 to 6.8 with a 7.0 on a long down hill run. Now for mileage and remember I tow around 5700lbs. This has been an poor test as we are driving in 30 to 40 mph winds with gusts up to 55mph yes my knuckles are white.I drive on cruise about 62 mph but like other have said when off cruise I find myself over 70mph with the added power. As for as 5/3 shifts seems better, but what I have found is that it stays in 4th gear longer giving me time to disengage cruise control. This is my first report, I am amazed at the improved power from stop to 60 mph and coming on interstates I have been changing altitudes from 1000ft to 7000ft and can tell great difference.

"I have started my trip from Wickenburg AZ (N/W of Phoenix) to Indiana after loading 5star.
