What causes lack of performance?
To make it short, I've always doubted if my IS350 really has 306 horsepower. The other day, I "raced" a Toyota Matrix and lost. The car was in D and I just floored it at a light. I was tied with it but the Matrix began pulling after 70 MPH. Couldn't believe I lost to it. And I've raced my friend's 2.0 Genesis Coupe and we always tied.
Now I'm wondering if something is wrong with my engine. Everything is up to date with maintenance including spark plugs changed 10K miles ago. Been watching videos of 0-60 times on the IS350 and mine is no where near as fast as most.
Today, I went to try my 0-60 time and it took almost 7 seconds in D with ECT Power on and traction off. When most IS350's I see on YouTube take off, it changes to 2nd gear when redlining at about 40 MPH. Mine changes to 2nd at 30 MPH and it's redlining. The mods I have are a CF hood which reduced some weight, Takeda intake, and exhaust.
Any suggestions on what to do to increase engine performance?

Ooo you gon learn today....
I will save you the "do the search" lecture but to save you some time I will summarize what everyone will eventually say.
Turn off your driving assists. Leave in drive. Turn off power ect. Quarter of a tank (if you can help it). Nobody riding shotgun.
You loose to a matrix again, debadge and apply 250.
LoL hope this helps, happy "racing."
