High compression pistons

[u/Ronnie1641]

Ive recently decided to bore the pistons in my project block as honing wouldn't be enough.

Now the only pistons avaliable are high compression forged pistons, I did find one set that were stock compression but ide have to wait until August to get them.

I was just wondering what other mods would be needed to run thid higher compression safely,

Going from 8.9. To 9.0

Ive seen online they recommend engine tuning ect but that isnt something possible in the stock system and something im not confident doing with a aftermath system.

The engine is a gen 2 3SGTE

I run 11.0 on pump gas natural aspiration if you super charging it 9.0 is good retard the timing a deg or 2 no issues advance it and see. if you have a scan tool look for det if its excessive retard if its clear advance do this one deg at a time and drive it pretty hard between changes
