Power Pages - Mitsubishi Lancer Evolution IX MR

A smile on everyone's face indicated that final power figures gains of 41hp and 17 lb ft of torque at the end of the day made this a successful power page for the Mitsubishi EVO, which narrowly missed the 300whp marker. Those who are curious in terms of the EVO's air/fuel ratio before and after modifications will be glad to know at 6500rpm, the dyno recorded an 11.49A/F for baseline, an 11.62 A/F for intake, an 11.31 A/F for exhaust, and finally a 11.61 with the Gizzmo. Although conditions within the air/fuel ratio were at acceptable levels, we couldn't help but to address how much smoother the dyno graph would have been if the proper tuning was performed using an aftermarket standalone ECU or reflash unit. Look for part two as we look to install a set of camshafts, use our Gizzmo once gain to turn up the boost and heed our own warnings with an aftermarket fuel setup for this EVO MR.
