okay guys under the e38 files, in engine>airflow>electronic throttle>desired throttle area there are several tables labeled map a through d.. inside there are tables which has tps percentage on the x axis and an unknown on the y axis.. can this be adjusted by lets say 15% to increase throttle response? I tuned a 08 silverado 5.3 and i couldn't get the truck to respond to my throttle, there was a lag time from the instant i depressed the throttle to the rpm increase. I disabled all the torque management, maxed out area rate limits and ETC limits tip in management ETC. everything you can think of, the last thing I have not touched is this table. Has anyone modified it? I have seen some guy named Chuck Cow?? that has messed with these tables to increase throttle response.. but there is a warning that says modifying such tables could fry the pcm..any help?
