1.8t Stroker compression ratio

[mike.ford84]

I am currently building up a Big Port 1.8T stroker engine using a TFSI crankshaft.

Looking at my options at the moment with regards to piston compression ratio.

At the moment my options are 82.5mm 8.5:1 & 9.5:1 CP stroker pistons from PAG Parts:

I'm fitting a GT2871R to it, and want the best spool posssible so thinking at this stage 9.5:1 maybe better, but at the same time I don't want to compromise tuning potential with the slightly higer comp ratio??

Any suggestions/Help would be greatly appreciated

9.5:1 my preference...
