I got my GT performance pack for around $22k usd. $5k gets a whipple and over 700 horses. They have a ton of potential and used are becoming cheap.

stock I used my phone app on the same road and tested my GT and it was 1-1.5 mph slower than my zr1 stock. After intake cat back and tune its about 1 mph higher. So basically a Z with a cat back is a good match for a bolt on 5.0. Top end the Z should still pull away.
