A bigger turbo alone runs out of fuel. The APR Stage 3+ PowerMax GT2563S Turbocharger System solves airflow and fuel together, with the factory ECU in control. The Garrett PowerMax GT2563S is the same direct-replacement turbo APR uses on the MK8 Golf R, adapted to the GTI with a dedicated fit kit and hardware. To feed it, APR adds Multi-Port Injection (four 980cc ethanol-compatible Bosch Motorsport injectors on the factory intake manifold) and the genuine VW MK8 Golf R brushless low-pressure fuel pump and controller. High-range MAP sensors let the ECU measure and report boost above the factory sensor limits. APR Stage 3+ ECU software is included. The factory ECU runs the direct and port injectors together, monitors low-side fuel pressure full time, and reduces torque if pressure drops. Torque-by-gear management and a launch torque strategy are built for front-wheel-drive traction, with full power from 4th gear. Choose the 350 WTQ or 400 WTQ file on 91, 93, or E85; the 400 WTQ file requires the APR DQ381 TCU Upgrade. Software flashes at home with APR Ultralink or at an APR dealer. The result: up to 521 WHP and 410 WTQ on E85, up from 249 WHP and 303 WTQ stock, and a best 60-130 mph of 8.64 seconds (E85, Dragy, best of four runs). OEM-style cold starts, idle, diagnostics, and factory safety strategies stay intact.\u003cbr\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003ch3\u003eFeatures:\u003c\/h3\u003e\n\u003cul class=\"productpage_list\"\u003e\n\u003cli\u003eUp to 521 WHP and 410 WTQ on E85 (High Torque file), up from 249 WHP and 303 WTQ stock; 449 WHP and 402 WTQ on 93 octane\u003c\/li\u003e\n\u003cli\u003eBest 60-130 mph of 8.64 seconds on E85\u003c\/li\u003e\n\u003cli\u003eGarrett PowerMax GT2563S, the same direct-replacement turbo as the APR MK8 Golf R kit, with GTI fit kit and turbo hardware\u003c\/li\u003e\n\u003cli\u003eAPR Multi-Port Injection: four 980cc ethanol-compatible Bosch Motorsport port injectors, fuel rail, distribution block, and harness\u003c\/li\u003e\n\u003cli\u003eGenuine VW MK8 Golf R brushless low-pressure fuel pump and pump controller\u003c\/li\u003e\n\u003cli\u003eHigh-range intake manifold and charge pipe MAP sensors for accurate boost measurement above factory limits\u003c\/li\u003e\n\u003cli\u003eAPR Stage 3+ ECU software included; direct and port injection both run on the factory ECU, with no standalone ECU or injector controller\u003c\/li\u003e\n\u003cli\u003e350 WTQ and 400 WTQ files on 91, 93, and E85; the 400 WTQ file requires the APR DQ381 TCU Upgrade\u003c\/li\u003e\n\u003cli\u003eTorque-by-gear and launch torque strategy built for front-wheel-drive traction, with full power from 4th gear\u003c\/li\u003e\n\u003cli\u003eAPR Fuel Pressure Protection monitors low-side fuel pressure full time and reduces torque if it drops\u003c\/li\u003e\n\u003cli\u003eOEM-style cold starts, idle, diagnostics, and factory safety strategies retained\u003c\/li\u003e\n\u003cli\u003eECU and TCU software flash at home with APR Ultralink or at an APR dealer\u003c\/li\u003e\n\u003cli\u003eHigh-flow catalyst files available: boost control recalibrated to prevent overboost, up to 534 WHP on E85 with a high-flow catalyst (not included)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"APR","offers":[{"title":"Default Title","offer_id":50882443477185,"sku":"T4100009","price":5695.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0005\/7773\/2663\/files\/41badb1c8ca1f1cef6d5bcb5c0e2778d7e2cdb16.jpg?v=1793642038","url":"https:\/\/www.urotuning.com\/products\/apr-stage-3-powermax-port-injection-lpfp-turbo-system-vw-mk8-gti-t4100009","provider":"UroTuning","version":"1.0","type":"link"}
