Today I noticed that my cars turbo will spool fine until about 5psi (very slowly though) and then it will ease its way up to 15. However, sometimes when I hit 15psi it bounces down to 5psi and starts to respool. Normally it spools quickly and the turbo reaches 15psi and doesn't drop unless I release the gas.
I recently put a fuel injector cleaner into the car it says it's safe for turbo-charged vehicles and doesn't affect air sensors etc. I used wynns fuel system cleaner.

Also with my transmission I've never had a problem with it before. If I drive the car and heat the engine up and then turn the vehicle off, remove the transmission fluid reader the transmission spoofs smoke and creates a smell of burning fluid. I've also noticed that for some reason whenever I go to put the car into gear-5 it grinds unless I'm <3000rpm which is also unusual.
Any ideas, thanks
