Honestly, if anyone knows there stuff is Terry and his crew. Couldn't be any happier with my ride. After all this time it's actually drives like a new car. The idle, response, the hanging, the power, and the fuel economy. Honestly, I couldn't recommend anyone else. All GM Automotive. For any Holden LS engines, drive line and fabrication work. I highly recommend the boys at All GM Automotive.
So don't be shy ring Terry and his crew to see what horse power he can achieve with your ride.
10/10 from me.😎👌👍
