which cometic head gasket will bring the na bottomend closest to the turbo compression.
ive got a tune on my computer which made 300hp so if i get the na compression close to the turbo can i just use the tune ive got.
no it needs a retune joe you cant tune a car then slap that tune on another car the result will be pinging and detonation , leaning out , running excessivly rich ect ect
Approximately
Changing from 1mm head gasket (std) to 2mm should bring your CR from 9:1 down to 8.2:1. And 2.5mm gasket will bring it down to 7.85:1.
CC it!
