Dinan Cars - Stage 1 Performance Engine Software

The Dinan Performance Engine Software safely increases turbo-boost pressure from the stock 16 to 19 psi, along with properly retuned fuel mixtures, ignition timing and full map rescaling. In fact, over 2000 lines of code have been addressed, producing substantial increases in power output while maintaining the civility and reliability expected of a Dinan performance product.

Top Speed Governor Removed. With Dinan’s software, the X will be capable of achieving its natural top speed as the governor has been removed.
And as always, Dinan matches the new car warranty coverage for up to 4 years or 50,000 miles, including the possibility of consequential damages. No one offers better performance or backs it up with such comprehensive warranty coverage.
The results of Dinan’s tuning are nothing short of breathtaking, with the added boost and related recalibration producing maximum output of 610 horsepower at 6000 rpm and 575 lb-ft torque at 3500 rpm.
