The badge alone is not enough: in this generation, the same engine designation came in different power outputs, each with its own calibration. Check the power output in your registration document and find the matching row.

Toyota Celica tuning: what changes
More power and torque without an ECU remap or replacing any parts. The tuning module only adjusts the engine sensor signals. Your manufacturer’s warranty is preserved: the ECU software is never changed, and the module can be removed at any time.

What makes the Toyota Celica special
Toyota Celica tuning: the 1.8 VVT-i and the T-Sport
For Toyota Celica tuning with a tuning box, the T23 is the place to start: the last generation, launched in November 1999. It came with a 1.8 VVT-i (1ZZ-FE) with 143 hp or, as the T-Sport, a 1.8 VVTL-i (2ZZ-GE) with 192 hp. Neither engine has a turbo or a supercharger, so the GAN GA+ is the module for both.
Each T23 version came with a six-speed manual gearbox. The earlier T20, built until 1999, had a 1.8 with 116 hp and a 2.0 3S-GE with 175 hp; these use the GAN GA+ as well.
Toyota Celica chip tuning: questions
What power does a tuned Celica T-Sport make?
The T-Sport goes from 192 hp and 180 Nm to 215 hp and 202 Nm, and the 1.8 VVT-i from 143 hp and 170 Nm to 160 hp and 190 Nm. On a naturally aspirated engine the GAN GA+ gives up to 12% more power; these are the stated gains for this engine type, not a dyno reading of your car.
Does Celica chip tuning cover the T20 2.0 3S-GE with 175 hp?
Yes, the 2.0 with 175 hp and 186 Nm works with the GAN GA+ and goes to 196 hp and 208 Nm. The 1.8 with 116 hp and 154 Nm goes to 130 hp and 172 Nm.
Is a tuning module the same as a Stage 1 tune?
Not quite. Stage 1 usually means an ECU remap without replacing any parts. The tuning module also works without replacing parts, but it does not change the ECU software: it adjusts the sensor signals, comes off in about a minute, and the OFF button in the app restores the factory settings.
