[QUOTE="cdemart2, post: 466528, member: 5497"] If you're talking about Jim's Performance in Maryland, send him your harness if you don't want to DIY, but have your pcm tuned elsewhere. I had him tune an LQ4 to be used behind a non-computer controlled automatic. Basically a manual trans tune. He left the auto trans functions in, left torque management in, turned off a bunch of trouble codes that you want enabled, and whatever was done to the fuel/timing maps caused bank 1 to run very rich at high load. He doesnt do anything to add power aka "hot tune". Told me to not hook up the vss but did nothing to the idle maps, causing it to come down to idle too quickly under coast and stall. Basically ran like ****. Mail order tunes are only worth the cost of the license to unlock your vats and turn off emissions functions so you can drive it onto your trailer to take to a dyno. If the closest dyno was 5 hours away that's how far I'd be driving to have it tuned. [/QUOTE]
