Was with the impression the TB45 was not delivering all it was supposed to. Car was feeling very constrained at higher RPMs and not liking to work on that range. I had already used those fuel system cleaning products a couple of full tanks ago to some improvement but still not yet where I was expecting the performance to be. Air and Fuel filters brand new as well.
Then I took the GU on a trip where I had to drive it for hours on the highway, with opportunities to rev it higher for overtakes and to keep it revving up hills and I really think the cleaner finally got rid of any clogging or whatever was holding it back. The car came back from the trip so much nicer to drive, engine is so much readier on the throttle and I dare to say even more torquier then before.
All the TB45 was needing was a good stretch!
