Volkswagen Jetta 2.0 FSI 147 bhp

The new generation of FSi engine provides direct injection and takes refinement and economy to a new level. With a Celtic Tuning remap these engines get a nice increase in mid range torque, and with more power at the top end, coupled with a raised rpm limiter, makes for a nice improvement to performance whilst being of no detriment to fuel economy. The flat spots are also eradicated from the power delivery. We develop all of our software on the rolling road to ensure accuracy in terms of both power delivery and also to ensure fuelling, boost pressures and exhaust gas temperatures are all within tolerance. Our aim is for maximum power whilst maintaining optimum reliability.
