Frequently Asked Questions

Do I need a tune after installing this pack?
Yes — an ECU remap is required to correctly calibrate boost, rail pressure and injection timing for the 44 mm turbo and +30% nozzles.
What power can this support?
With the right supporting mods (exhaust, intercooler, intake) and quality calibration, the combo supports roughly 220–280 RWHP on healthy 1KDs.
Are the nozzles a direct fit?
Yes — designed for OEM 1KD injector bodies. Professional assembly with flow-test & shimming is strongly recommended for consistency.
Do injectors need recoding after nozzle install?
If the injectors are rebuilt and new calibration data is produced, your shop may provide updated codes. If only nozzles are changed and bodies retained, existing codes are often used; trims should be checked post-tune.
Will it work with the stock intercooler?
Yes, but a quality upgraded intercooler is recommended for sustained power and safe IATs, especially on higher boost targets or towing.
What else should I replace during install?
Replace oil feed/return gaskets, consider new oil feed line if contaminated, inspect charge pipes for leaks, and always prime the turbo with clean oil before first start.
Is this legal and will it affect warranty?
Performance modifications can affect manufacturer warranty and road compliance. Check local regulations and consult your tuner/insurer before upgrading.
