should i tune ?

[vCo2v]

I'm still on the stock afm, fuel system, and turbo. My mods are
full 3 inch down pipe
high flow cat
exhaust
apexi intake
Bosch 110 bpv

And I just installed an ams intercooler with the cxracing hard pipes.

after the intercooler I noticed a huge difference in the turbo. It spools quicker and harder. My next immediate upgrades are arp studs with a stock head gasket.

Would I benefit right now with a wideband and a safc2?
Also does the 57 trim Ct26 spool slower than the stock Ct26?

Great start!

Wideband / SAFC - Dont worry about a wideband / safc until you upgrade injectors. There will be very minimal gains. i.e. not worth it.
57 trim - Shouldnt be much slower. About the same. Wont see much gain in power until injectors and safc.

Then you will be ready for a tune.

Focus on the Fuel system next.
