I just installed a used banks sidewinder turbo on my 89 f350 7.3. Im only getting1-4 lbs of boost. I installed the same setup on my 86 with a 6.9 and its night and day. Probably getting 13 lbs of boost on the 6.9. I have no muffler just a straight pipe to the front of the rear wheel. Is that too much restriction. Should i make it shorter. Does the fuel need to be turned up. Its the same system, whats wrong
