1988 chevy truck turbo 5.3l

1988 Chevrolet Silverado 3500 Additional Info:

I have the right to end auction at any for any reason. Truck is for sale locally too.
Has a 5.3 iron block that has been gone though. est. 550 hp 550 trq est as tuned at 10psi boost. On 91 oct ethanol free fuel.Tuned rich at 11.4 in boost with conservative timing. Tuned with HP Tuners software. Room for improvement on tune if you want to push the limits more. Just backed off for safer tune incase it got cheap fuel. Seldom stalls when warm coming to a stop. Think it is the iac I will be trying to fix this before it sell. Also pulls to the right under hard braking. Think it needs a brake hose.
