It has a "extremely" restrictive intake and shorty little tube headers. The motor WAS NOT BUILT to make a bunch of crazy ass horsepower but rather - be very drivable for my darling bride. The car weighs in a exactly 2975 pounds so doesn't require too much to get it scootin' right along.... just ask Chris Gonzales.... HAHAHAHAHAHA
This was the only power pull I videoed ---- and the blue smoke was due to it being PIG FAT.... that all cleared right up in subsequent pulls. Advanced Motor Performance did the tuning --- and they only work on big HP LS stuff.... like 1500 twin turbo Vettes -- and several 750 to 900 hp late model Camaro's and CTS V's.... that's all they had in their shop. AMP is located in Arlington Texas....
