During the time I found a good deal on a set of D2 racing shocks. They are extremely sensitive on street and I can feel every little bump on the street (not comfortable at all) but at least rock solid on street corners.
Also I am having less wheelspin when giving her full throttle from a stop sign

Here is the update:

Boost as much as your fuelling is good for! I have stock head and head bolts too. 7300 rpm has been just fine. I can vouch that the stock head can withstand past 8000rpm as I accidentally found out twice ( dropped it in 2nd instead of 4th on the dragstrip.. whoops ). I wouldn't set it at 8000rpm though lol. My factory tach won't read past 8000rpm so Im not too sure what it went too. Is It bad when the 1nzfe sounds like an F1 engine? jk.
Set it at 7300 if it still makes power.

I just looked at your picture few posts above... make sure your pipes are bead rolled or the dyno session may get pricey if they have to keep putting back blown off intercooler pipes. May be fine at the boost you're at now........
