SBR Custom Merge Tune - GM Gas (Email Tune)

SBR Custom Merge Tune - GM Gas 🏁 A real tune built on your car's actual read. Not a generic file blasted to everybody. You send us your stock read, we merge our proven SBR calibration into your exact file, and you flash a tune dialed for your combo. Fits: Nearly every gas GM platform HP Tuners supports, from Cavalier and Sunfire Ecotecs and Cobalts up through LS trucks, F-bodies, Corvettes, the 3800, and the 4.3 Vortec. Pick your platform from the dropdown. If you do not see your combo listed, message us before you order and we will tell you straight up whether we can do it. Driving a Crown Vic, Grand Marquis, or Marauder? Those live on our Panther platform listing. You'll need: HP Tuners MPVI interface, VCM Suite, and credits to write your ECU. If you already read and write your own ECU, you're set. Every platform here reads and writes through the OBDII port. We do not list anything that requires HP Tuners' send-in ECM unlock or upgrade service, so you will never buy a tune and then find out your controller has to be mailed to Illinois first. That rules out Global B trucks and SUVs, the C8 Corvette, the 19 ZR1, the V-series Blackwings, and the 2.7 turbo. If that's your rig, reach out about our mail-in service instead. How it works: Pick your platform and buy your tune Reply to your order confirmation email with your stock read file, your HP Tuners interface serial number, and your full mod list and setup We build your file and email your finished tune back, usually within 24 to 48 hours Flash it and go get that W 🏆 Tell us everything in that email. Cam, head work, intake, headers, exhaust, injectors, throttle body, converter, boost or nitrous, transmission, gear, tire size, and the fuel you're running. The more you give us, the better your file. We'll come back with questions if we need them. Cavalier and Sunfire guys: we still build your file around your exact cam and intake. We just collect it in that follow-up email now instead of a dropdown, so you can tell us the whole combo in your own words. Comp 113200, 113300, 113400, a 272 or 280 regrind, big runner intake, whatever you're running, just say so. Your file is locked to you. Every SBR merge tune is locked to your HP Tuners interface serial number and to your VIN, so it will only write to your vehicle with your interface. That's why we ask for your serial when you send in your read. If you later change interfaces, swap ECUs, or sell it, just reach out and we'll get you sorted with a new file. Fuel matters. 91 and 93 are pump-gas tunes. Race fuel tunes are off-road use only. Do not run a race fuel tune on the street or on a vehicle with catalytic converters you care about. Tell us the fuel you're running, and run the fuel your tune is built for. Built by tuners who live this stuff. Tuned to win. By ordering you agree to our Email Tune Policy.
