We specialize in cam swaps, DOD/AFM deletes, and performance upgrades like headers, intakes, supporting mods — and the most important part: tuning that makes it all work together. Our main focus online is pre-written tune files delivered by email.
A “pre-written tune” is a proven tuning approach built around common combinations (stock, bolt-ons, cam) on GM LS and HEMI platforms. It’s for people who want their setup to run right without guessing. You send us your factory read file so we can apply the correct changes to YOUR exact vehicle and send a tuned file back.
These tune files are ideal if you have a common setup and you want:
If you’re unsure which product fits, text your year/engine/mod list and goals and we’ll point you to the right option.
Important: tuning results depend on mechanical condition, fuel quality, and the exact build. If something is off mechanically, tuning can’t “tune out” a problem.
Choose the product that matches your platform. Each card includes a “tune in action” video and a direct product link.
We offer a $20 discount when you pay using a direct-pay method: Cash App, Zelle, Chime, or Apple Pay. You can go through checkout to see the total with tax, then subtract $20 from the after-tax total. For exact discounted pricing after tax, call or text 910-231-5505.
Built for common cam combos on 1998–2006 GM trucks. Great choice if you want a strong idle character with clean drivability. Email us your factory read file and your mod list.
Popular options for 2007–2013 trucks. Great for stock-to-cam builds looking for improved response and drivability. Send your factory read file and we’ll build your tuned file.
LV3 V6 platform-specific tune option aimed at improving throttle response and drivability. Email us your factory read file so we can apply the correct changes.
HEMI tune file options for common street builds. Send your factory read file + mod list and we’ll return your tuned file.
For aggressive combinations that need a stronger performance approach. If your build is “more than basic,” start here.
High-performance file for 4.8/5.3/6.0 trucks built for strong output with real-world drivability. Email your factory read file and full mod list so we can set it up correctly.
Want us to do the cam swap / DOD delete and handle the tune? Contact us and we’ll plan the job.
For local customers, we can handle the install work and tuning as a complete package. The cleanest results come from doing the hardware correctly and tuning it correctly.
If your 1997–2006 GM / Chevy P01 or P59 PCM got bricked during tuning or flashing, this mail-in service is built to recover it. Common causes are voltage drops, interrupted writes, laptop sleep/USB disconnects, or failed bench flash attempts.
This service targets common failed-flash situations that leave the PCM stuck, unreadable, or non-communicating.
We recover the module and verify it communicates correctly before sending it back.
Price includes the licensing credits required for us to properly restore / re-license the flash where applicable.
Tip: If you’re seeing X7F-type errors, don’t keep hammering “write” attempts — repeated failed writes can make recovery harder.

Include your order number in the box and (if you can) a quick note describing what happened during the flash.
This is a repair/recovery service (not custom tuning). Physical damage, water intrusion, or burnt components may be non-repairable. If it’s beyond recovery, we’ll contact you before proceeding.
If you’re near Wilmington (Leland, Castle Hayne, Hampstead, Burgaw, Carolina/Kure Beach), we can handle the hardware install and the custom tune as one complete package — with published part numbers and a clean, correct install.
These are bundled package prices including parts, labor, and a custom tune using OEM GM parts. Final price can vary by exact year/engine/trans/mod list.
