I have a 1989 Volvo 740 Turbocharged. When I get on the accelerator my Turbo gage does not register that the turbo has kicked in. In fact it has not kicked in, the car is just accelerating normally.
Most likely it's time turbo.
Possibly,the ethanol doe,s not burn as hot,try high some premium and a little octane booster,should let you know,if turbo is right or not.
