I have to agree.
I run delco stuff in all my v8 rides the folks at pcm hacking are on the ball and really helpful.
It cost me only a couple of hundred bucks to setup with the basic gear for reading and writing to memcals.
And there are dozens of tunes and variations to choose from. in the very least it is a starting point and if needed the rough edges can be knocked off by a tuner with a dino.
The tuner pro software is so easy to use the dino guy probably uses it already.
Im planning on a turbo 5l and 4L60e and there is a tune free to download on pcm hacking.
Cheers
