Just got my 97 f 250 with 7.3 turbo and 5 speed running again. I am having major issues with turbo lag... namely the turbo doesnt even begin to spool up at all until around 2000 to 2500 rpm.
It is just flat unresponsive up to that point. Especially in first or second gear. I have to throttle it fully floored to get up to that rpm then the turbo comes in. By then it is time to upshift.
Is this normal?? the boots are new and not leaking, the turbo doesnt have play in it. the exhaust is 4 inch straight tubing. The valve on the outlet end of turbo is blocked open, air filter is K&N new. The guy i got it from showed me some paperwork showing it had a different blade set and bearings put in not even 2 years ago
