The customer assumes all risk if this turbocharger purchased and installed without first confirming the required software is available. No returns are accepted for installed turbocharger kits. TTE720 Performance turbochargers are designed for 700PS+ but the real restriction on this car is the small single charge cooler, so the power of around 650 on 99ron is to be expected unless the cooler is addressed. Upgrade downpipes, sport cats and full exhaust are recommended as upgrades to the turbo intakes and system for max performance. Equilibrium Precisely balancing our turbochargers is a key critical factor to become a TTE upgrade unit as longevity and performance are paramount. Good balance improves acoustics also. Subsequent great care is taken with all TTE turbochargers to achieving our balance standards. Firstly parts are balanced at slow speeds up to 2800RPM in multiple planes using our single parts machine, then components are assembled and then the CHRA are dynamically balanced, but this time depending on application at up to 250,000 RPM in multiple planes using our in house VSR machine to acquire the ultimate equilibrium, to a standard far higher than OEM. Each turbocharger is supplied with a serial numbered balance test result document.
