Stage 1 tuning is the most common option. These tunes and mods generally do not require additional mods. Simply add a stage 1 modification and go. Even though most stage 1 tunes don’t require mods there are still some good mods to couple with a stage 1 tune. An intake and exhaust are popular stage 1 mods to include with the tune.

Naturally aspirated engines may only see about 5-20 horsepower gains with these basic mods and tuning. However, turbo engines often see gains of 20-50+ horsepower with a tune only. Add in the basic bolt-on mods, and some turbo engines may even pick up around 100 horsepower with stage 1 tuning.

Stage 1 mods generally include intakes, cat-back exhaust, blow-off valves, and other basic bolt-on engine mods. Again, none of this is a perfect science. However, the general idea is that stage 1 tuning and mods are basic things that usually don’t require further modification.

Typical stage 1 mods are generally a straightforward DIY fit and should work on a standard engine that is in good condition. Some examples of stage 1 mods include, induction kits, panel air filters, sports exhausts, fuel pressure regulators, a simple engine remap or timing changes, blow off valves/diverters and the like. Most of these easy to fit stage one mods are the first thing people will do on their project car. Just because they are popular it does not mean they are good mods or will add any significant power gains

For stage1, the price for stocking car function is 77USD.

Stage 1 Power boost first-stage procedure: regardless of turbine or self-priming engine, it can achieve 8%-20% power boost, and some turbines can achieve more than 30% boost without any modification!




Pcmtuner ecu data processing service process (functions such as power adjustment, immo off, dpf/egr remove, dtc shielding, etc.)

1. The customer reads the flash data of the ecu via the Pcmtuner (if the customer only buys the Pcmtuner dongle, they need to find another device to read the flash data, such as Tactrix Openport 2.0, Scanmatik 2 PRO,etc.)




2. Read out the flash data of the ecu + car model + ECU model and send them to the purchaser, verify that the payment has been finished, and submit them to the factory for revision [customer explains his needs (functions such as power transfer, immo off, dpf/egr remove, dtc shielding, etc.)]

3. The ECU Flash data processed by the factory is sent back to the customer, and is written to the ECU via the Pcmtuner
