How to order your tune: 
Car Year: Please type the year of your car. 

Fuel Type: Please select the appropriate fuel/octane you will be running. 

Flex Fuel Conversion Kit: Please select yes or no. Stock fuel system is limited to around E47 (half and half E85/93).  

Core Charge: There are a couple of options here. #1 - We can ship you a new PCM core that is already flashed with our file. The benefit of this is that you can keep your stock PCM to reinstall if you need to bring your car in for warranty work. #2 - we can send you a programming interface and cable which we supply with instructions, it will allow you to read your stock file, email it to us for modification, you can upload the modified tune on your stock ECU and send us a scan, then if additional tweaks are needed, we can modify the file again to perfect it. Upon returning this cable, you are refunded the interface/laptop core charge (deposit). Additionally a Windows based laptop is required. You can use your own or borrow one from us. The advantage of using ours is that it is pre-configured with scanning software and tools to help us assist you if you have any questions or custom tuning requirements. If you choose to keep the tuning interface and/or the laptop, that's fine. That core charge in that case will not be refunded. Core charges are based on 10 days, and there will be additional charges if cables or laptops are kept for longer periods. After 30 days, core charges convert to purchases.

Transmission tuning note: When sending your PCM core to us for tuning, or if selecting a new PCM core, we cannot tune your transmission because we cannot physically see or access the TCM. If you want your transmission tuned you must choose the rent interface or rent interface/laptop for a remote tune or in person flash.

Custom LTG Swaps: This option is for anyone looking to tune a vehicle that did not come with an LTG originally. You MUST choose this option if you are tuning a tube chassis car, sand rail, LTG engine retro fit into an older chassis, etc. Do not try to cheap out and purchase a tune from another year/make/model, we will find out and will not continue the tuning process if so. Be aware that when you purchase and start the remote tuning process you are purchasing our tuning services, not diagnostic services. The tune will be put together assuming you have all necessary sensors, boost lines, vacuum lines, etc hooked up correctly. Once you and the tuner have verified that the car is running well and you're both happy with the tune you have 7 days to request any changes. Once that 7 days has run up you can re-purchase our tuning services for your custom swap for $200. When doing a custom setup, there may be extra hardware (sensors, wiring, etc) needed for setting up the tune correctly. These things will be pointed out by your tuner if they are missing and will be required to move forward with the tuning. We will not cover these parts nor do we always carry those required sensors/parts.

If you are having knock (KR) related problems during your remote tuning sessions we recommend using Boostane. Boostane is a safe octane booster that actually works, unlike the generic "octane boosters" found at your local auto parts stores. We have noticed large spikes in fuel inconsistency since the beginning of the pandemic, so sometimes it's hard to point out if there's an issue with the car being knock limited or just the quality of fuel. While tuning if you add Boostane and notice the KR subside, then your problem lies in your fuel. If you add Boostane and it has no noticeable effect on KR, then it is likely that your car has a mechanical issue that is causing and/or being sensed as knock.
