Not much HP increase, unsure...
Unit does a great job of monitoring the engine and various other statuses but could use a ton of improvements in engine optimization. I really think they were overly cautious when programming for Nissan. Granted, I have a 4 cylinder so wasn't expecting massive gains but am very disappointed because I know this thing could do so much more.
Easy to install, on the fly tuning. Noticed better miles per gallon (about 3 miles plus highway, 2 in town) on performance tune running 93 octane. Better throttle response. Only other mod installed on this 08' A/C is a takeda short ram. Wanted to do exhaust header and underdrive pulley before programer, but got such a good deal, had to go with this first. Will work great with future mods. Satisfied.
