Alright... so recently my supra hasn't been running as well as it should. My turbo feels unresponsive and it feels like its losing power when I accelerate. For example I will hit 4,000 rpm and when the turbo spools it will drop down almost 1000rpm and then raise again. My first gear also feels very slow. It seems like it's struggling to gain speed and losing power when accelerating... sounds like its hesitating and cuts out for a second. I have no idea what is going on with it and this has just started about 2 days ago... I had an inspection done about 1 1/2 months ago and going in for an oil change tomorrow. Any suggestions what the problem could be?

no engine light comes on, but my coolant light does. I've cleaned and refilled my reservoir... the radiator coolant is clean aswell.

How do I tell if its boost leak, or fuel cut?... I'm also running stock everything except for a K&N fipk... so boost is also at stock levels.

well took it to the shop and apparently its my clutch, does that sound right? And if so what is a recommended clutch to get thats available in canada? I might be doing some upgrading in the winter since I will be storing the car... thinking about getting the rebuilt turbo, and maybe some others... so I would like a clutch that is good for now... and good for later

Well its definitely the clutch... the car had problems even reaching 20km/h, would barely move off the start.
