Body type Transmission

ALDL port under the dash (1994–1995 Cable Loan)

Required if you pick Cable Loan. Most ’95 LT1/L99 vehicles are 16-pin (wider on the top row); a few still used the older 12-pin square connector. Most ’94s are 12-pin, but please look and choose the one you have so I send the correct cable. If I do not have your size in stock, Cable Loan will not be available.

12-pin (square connector) 16-pin (wider top row)

With JavaScript, unavailable packages for your year/setup are disabled automatically. Without JS, pick a package that matches the Get Tuned! page rules — the server will re-check.

3. Vehicle details

With JavaScript, only fields that apply to your package appear. Without JS, enter at least engine and model (and other details you know); the server validates.

Engine Model / trim VIN (optional) Injector flow (lb/hr, optional) Injector brand / model (optional) Injector spray / nozzle (optional) Injector spec sheet (optional) Fuel pressure (psi, optional) Rear gear ratio (optional) Disable VATS Delete EGR Delete CAGS / skip-shift Comments for the tuner (optional)

Without JavaScript this is a compact field set. With JS, more package-specific options appear automatically.

4. Account & place order

An account is required so we can track your order, payment, and shipping. Scroll up to review choices before submitting.

Before you place this order

This form is only for selecting a package and vehicle details. Tune descriptions, method requirements, cores, shipping, and post-purchase service are explained on the full Get Tuned! page. Please open that page in a new tab and read it completely if you have not already.

I have read the entire Get Tuned! page (Basic/Power, Postal/Email/Cable Loan/In-Person, payment, shipping, and service notes), verified my choices above, and accept the risks of remote PCM tuning.
