again.. make sure timing is pulled at 12PSI.
You are running a stock motor out of a camry with cast pistons and a compression ratio of 10:1 with the carbon deposits

10:1 compression
[/b] actually the 06- models are 9.5 and the 07+ are 9.6
And I will add to that with a couple more
I guess we feel free to make up our own Compression ratios for our motor. LOL...bro, it's no where near 10:1 compression.

To raise compression from 9.6 to 10.1, you'd need about .04" of carbon buildup in each cylinder. That's enough carbon buildup, that you'd be able to scratch it off with your finger nail. I have NEVER seen that much carbon build up in an engine before.
If this was true, engines would make more power as they get older. It's quite the contrary.

I guess
Cast pistons dont mix with F/I.. you cant have both and expect reliability without pulling timing
I have a chipped piston that shows 12PSI is too much for this motor without pulling timing. I was "tuned" also
I have a few turbos and a few motors so I have expierence with this car

i have added timing thoough out my whole power band and thats cause my s/c ecu keeping pulling timing from me so my tuner added timing to my s/c cu to make up from all the timing being pulled. but i still dont have any real real timing then my car needs or wants.

I've seen up to 14psi when I was tweaking my boost controller. I had set the AFR really rich in that area on my fuel map on the hydra as a precaution.
After that, I had it consistently at 10-12psi after the boost controller tweaks.
Yes, timing has to be pulled if your on boost, and have an appropriate AFR for the setup.
12psi is normal for high boost. Countless people run that and are fine.
Stock Sleeves are good for about what 400-450whp. That guy in puerto rico is making more than 450 on stock sleeves (CRAZY! lol)
Stock Pistons on premium gas about 350whp, and about 400whp w/ race gas.
#'s may vary, but these are on good tunes, with good setups, and standalones.
The way the car is driven is another factor, and how good the maintenance was obviously.
That amount of carbon build up that guy is talking about is ridiculous. I would be more worried about hot spots.
Water/Meth injection steam clean anyone? =)
