STI Stage 1 Tuning Package - 1,850.00 inc. VAT

Our budget Performance Packages are designed to give maximum performance for minimum cost and fully MOT emissions compliant.

When tested against prodrive performance packages on any given model the Stage 0.5 Package gives significantly better results. This is due to all our remaps being tailored to your vehicle allowing us to fine tune the ecu re-map specifically for the tollerances of your engine. This is unlike the Prodrive ECU re-flash which is a one size fits all generic map

Price is inclusive of fitment, mapping and rolling road tested.

Flywheel Power Output:

GRD Jap Style Back Box - Subaru Impreza New Age angled Jap style back box gives approx 2-3 BHP gain over conventional style back box.

Sports Cat - 100% MOT friendly. Allows the high flow of exhaust gases, although not to the extent of a De-Cat section, yet still removing harmful emissions. 2.5" Diameter.

GRD 2nd De-Cat Pipe - The cat pipe replaces the 2nd cat on a New Age Impreza, which can be removed without messing up the ECU and is still MOT friendly. This can also be supplied with a high flow cat.

Free Flow Air Box Panel Filter - High performance replacement for the original panel air filter. Constructed from a cotton weave which increases air flow by upto 40%.

EcuTek ECU - We use EcuTek software to reprogram your ECU via the diagnostic port of the car. We retain all the car's clever electronics but re-map ignition curves, fuel maps and the closed loop boost control system. The ECU remains programmable so if in the future something needs to be changed then we can. The only way to tell that that either conversion has been performed is to drive the car. There are no visual clues. Even the Subaru diagnostic tool does not show that the ECU has undergone brain surgery.

Rolling Road Tested - Our Dyno Dynamics chassis dynamometer measures engine power via the driving wheels in an accurate and repeatable method. Your vehicle's dyno runs are recorded in real time, and printed out in full color for your records.

Optional Extras

Please call us on 07973 787812 or E-mail to discuss any optional extras and prices.

Exhaust Downpipe Heat Wrapped Or Ceramic Coated - This serves 2 purposes. To reduce heat soak into the engine bay and to keep the internal pipe wall temperatures up to aid the removal of waste gases through the exhaust system.
Heat Wrap 50.00 inc. VAT Fitted

GRD Subtle Back Box - The back box is the original style Scooby design back box, subtle in terms of looks and sound.

GRD Water Spray System - The system automatically sprays the intercooler when the turbo boost pressure reaches a preset and fully adjustable level. This helps to reduce charge temperates, which in tern allows greater ignition advance giving a significant rise in Horsepower and Torque levels. The car's standard intercooler spray warning light also gives warning of low water levels making this system reliable and easy to use.
130.00 inc. VAT Fitted

GRD Cold Air Intake - By eliminating the standard airbox resonator and snorkel we are able to source cold air directly from custom vents in the front foglight cover. This helps to dramatically increase airflow to the standard airbox, lowering inlet temperates and in turn give a significant increase in both power and torque.

This package does require STI foglight covers, however we can offer these as an option on most WRX models.
