Question CAM advance

I have a question about CAM advancing.
I am running round tooth oil squirter block in my 92 740.
Upgrades i have done.
IPD turbo cam.
Chipped.
DO88 intercooler.
TD04H-15G.
MBC 10psi max boost.

So my question is i found a sweet spot with 5° CAM advance, is there any harm going that far?
I got a far bit of torque at the bottom end, turbo spools really fast. There is no turbo lag i can feel, infact i hear a lot more tubro spool whine when I get on it. I am at fill 10psi boost by 2500rpm when I step on it.

Should I be worried about extra heat or anything like that?

If you are running premium and haven't heard any bad noises. You will be fine. I run 2 advanced on my turbo and 6 advanced on my n/a car.

Went the opposite on the autocross car, 3° retarded it's a tiny bit laggy but it's a monster mid and upper rpm range.

Thanks, I run premium fuel with no strange noises runs pretty smooth once the ECU trained itself.
The car is so much fun to drive with that low to mid-range power and I still have enough top end to pass people.
If I were racing I would pull back on the cam timing because at 0 I would hit about 3500 RPM and it would just launch. since this is my DD I like having the low to mid-range power.
I have a feeling if the exhaust was upgraded from stock that would help out the top end.
