Well before I go and screw myself again....... can I adjust the ETC tables on my E67 PCM without fear of bricking the PCM???? I toasted a 0411 PCM a while back and I do not want to do it again.... gets awful expensive when you have to 'bribe' your local GM dealer to do a reflash on your PCM without a car attached to it!!! I am using a '08 Trailblazer LL8 cal and the throttle opening rates are ridiculously slow and need to be changed! Now I can see why these things seem so doggy, GM didn't let the throttle open up to make any power!!!!
Thanks in advance!!!
Mike
