on my st205 when i have the throttle pinned the turbo pulls hard until 4500-5000 rpm (depending on how long the engine has been running. little higher as the engine is hotter), and then i looses power and laggs hard un less i eas off the trottle, then it will slowly it start rev higher..This happens in all gears..on stock boost settings
I am thinking its a fuel shortage. i JUst changeds the fuel pres regulator but no difference and also the fuel filter.does it sound like a turbo problem to any one??or fuel shortage?
