I'm Awesome
thank you...i kinda knew that....but it's really what i needed to hear, to pull the reins back a bit, LOL....
Ask me how I know. haha
I used a mail order tune on my 489 stroker, it ran pretty well but now that I have tuning software and can see what was changed I know there is a lot to be had.
It could be that Blackbear puts more work into his mail order tunes, but the tuner that did mine only messed with the VE tables below 2000 rpm, added 4 degrees of timing across the board, and removed TM. To make up for the VE tables not being correct he just commanded 12.2 AFR in PE mode to keep things safe. Probably only took a half hour to make the changes.
That being said, for a truck that is pretty close to stock this would be more than acceptable.
