The only thing I have to say is the price of the computer was the highest cost of $1600 but to have 3-4k into it total. Hit the key and drive anywhere like a normal car is far cry from any bbc I ever owned since I was a kid. If I put a bigger turbo and tuned it, the car would run in the 9's no problem. You cant do that for another 1k for a upgrade turbo with a bbc and still drive it around like it was your daddy's stock Silverado.
Just out of curiosity how many miles have you pur with current combo to verify gas mileage and durability? and how many BB's have you wqlked by?
