Dyno result=Torque
I recently installed a plug-in "ebay special" tuning box to my Hyundai i30 Diesel. The results were surprising. I had in my mind that I'd be wasting my $110 on an internet scam but it actually works! Boost comes in earlier in the rev range and torque and horsepower are increased at every measurement. The i30 is factory tuned for maximum fuel economy and the air/fuel ratio reflected this; it was extra-lean but the tuning box fattened up the fuel mixtures.
