09 ISF 88K miles, muffler delete only all STOCK.
Spark plugs changed, New MAF, induction services done, oil good, coolant good, NO CEL lights, transmission feels smooth.
-For about 6 months now ive felt that my ISF has lost power, before by just tapping the gas i used to roast the tires and now even with TRACTION OFF i cant get a single squeal. I believe i hear an exhaust leak, but im sure that wouldn't cause so much power loss.
-Takes about 2 seconds for the power to kick in after WOT and when it does its not all there. Throttle response is super delayed, and overall torque has gone down by what i feel is about 30%.
Any Lexus master techs or good Techs in here that can guide me? I can take it to the dealership but with no CEL on they are not very helpful.
I will be getting a full stock exhaust soon and see if it helps since i noticed everything went down hill when i started messing with the exhaust.
ANY INPUT IS APPRECIATED!
