the cobra has been slow as balls forever, and recently it would barely rev-up! I got a fuel pressure gauge and it read 30psi when it should be at 45psi... so i ordered a aeromotive fuel press regulator and a bbk 255 fuel pump. which came in today, so it will be up and running this weekend when I find time to work on it! I haven't driven it for about 2 weeks now so im pretty excited!
