I'm very impressed with Stage 3's customer service. The tuner shipped quickly and my custom tunes were emailed the next business day. Great service!!! The tuner with the custom tunes really did help wake up my old 2V 5.4

My supercrew has high miles and struggled pulling our 5500# camper up hills at interstate speeds. This tune did the trick, can take most interstate hills at 65mph now with no downshifts. The download/upload process is a bit confusing, but once you get through that it's worth it. Only wish there was an 89 tune as they don't sell 91 around here.

Customer Question Does it come with a dash mount? And are you supposed to put it on your dash or is it a program and put it away

Asked by: Will Sanders - 4/29/2020
Customer Answer This device does not come standard with a dash mount. After you tune the truck, you can unplug the device and put it away, since the tune gets loaded and stored in the PCM. SCT does offer an X4 Windshield Mount here.

Customer Question If you buy bigger tires later on will you have to have the programmer re tuned or can you change tire size within programmer?

Asked by: Colton - 7/30/2018
Customer Answer The tuner can adjust for larger tires without the need for complete new tunes. Tire size is an adjustable option within the X4, though you will need to know your tire's revs per mile.

Customer Question What information do you collect to customize tunes? I personally have long tubes, no cats and straight dual Flowmaster 40 series. Is it custom to those specs?

Asked by: NewEdge2001 - 12/19/2017
Customer Answer 5-Star can custom tune for catless long tube header systems, and their tuning will take into account those particular mods to both avoid a CEL and to get you power gains.

Customer Question With "lifetime tunes" can I request tunes for both of my trucks?

Asked by: John Jones - 5/10/2017
Customer Answer Unfortunately, no. Our Lifetime Tunes Program only covers retunes on new parts you purchase from us that require retuning. If you need tuning for two different vehicles, your best bet would be to call us directly, since you'd need two different devices.

Customer Question I just bought the sct x4 from a place down the road from me, how much would it cost to have you set me up with custom tunes for it? I have a 2002 F250 Super Duty 5.4L V8 Triton.

Asked by: tim - 3/21/2016
Customer Answer 5-Star's Two-Tune Package is $160, while their Three-Tune Package is $200. However, your best bet would be to call us directly at 1-877-578-2433 so we can ensure there's no further information we need for the Super Dutys versus the F150s.
