feels faster but 0-60 time sux
When I first got my 06 tsx auto i put Cold air intake. My 0-60 time was about 8.4-8.5. Then I put my kazera 18" chrome wheels on but my tire size stayed the same. My 0-60 time was low 9's to mid 9's. Then I put my comptech header and exhast and my 0-60 time clocks anywhere from 8.2 - 9.1. WTF is going on here. Is it the wheels that are slowing down the car, road conditions/weather conditions, or is it just me using the stop watch incorrectly ( to late pushing the start button.) I know my car isnt a race car but I still want it to be somewhat decent. Thx

There are so many variables at work, it is impossible to say for certain... Here are some thoughts though:
Wider and/or larger tires do provide higher rolling resistance (in general). If the level of traction during a 0-60 run doesn't change significantly with larger tires, then the acceleration times will likely suffer a bit. If traction was never a problem, "pizza cutter" tires inflated to very high pressure would give you brisk acceleration and excellent fuel economy.
Contamination in the ATF can increase losses in the torque converter and during shifts. The fluid gets dirtier with each mile, albeit a very small amount. As contamination is added, the performance of the transmission drifts farther away from "theoretical".
Contamination in the oil can increase parasitic power loss in the engine. This goes without saying.
Fuel grade, drive belt tension, and the condition of the ambient air, air and fuel filters, and spark plugs all have a small but cumulative effect on performance.
I wouldn't expect a header to make an extraordinary change in acceleration from 0 to only 60mph in the real world, but tires and some of the other items all added together might affect it more than you would think.

How much does your chrome wheels and tyre combo weigh compared to stock? My guess is a lot more than your OEM rims. If you have added 10 pounds at each wheel that is effectively the same as adding 160-240pounds weight to the car (multiplier of 4 to 6). That is a rough estimate anyway.
If you want better performance from your TSX - skip the trend towards fitting heavy, large rims.

i think you are experience what i was in my other post when i was talking about why my 04AT was so much slower than the 05 AT rental i had. Read the posts in there and about what simplyscion wrote about the intake! I also agree with psykotik maniak about the wheels because when i got my car back, it actually seemed sluggish at the wheels.....i have chrome wheels too....17's though

9.2 is really out of range. With no mod, my 0-60 time is around 8.0-8.2 depends on how I shift the SS. W/ all da mod I had now, it's around 7.5-7.7sec, depends on the road condition, launch, temp, and shift as well.
The Cold Air Intake might slow you down a bit as well, because 0-60 only involve 1 shift from 1st to 2nd, and the low rpm range will rob your time dramatically.

Chuson, Im talking about a/t not manual. and how the hell can cold air intake slow down your car. cold air intake sucks cold air to the engine, it doesnt slow it down. if cold air intake slowed down your car know one would buy it smart guy.

The TOV times are the more realistic ones, like you said.

You shouldn't time 0-60 with a stop watch because of the inherent margin of error involved (inaccuracy of pressing start/stop, parallax error reading the speedometer, variables like aftermarket wheel sizes). For truly accurate data you should use a G-timer or at least an OBD2 scan tool.
