Default Big torque stock block MT15 STI

Hey guys,

Got my 2015 STI tuned the other day at MSR.

Has basic mods (invidia catback, invidia dump, PW CAI, GFB BOV)

Have spoken to the tuner and he says this is reliable for the block which I do trust him as he has a really good reputation as a tuner/subaru guru.

Just wanted to get a insight on what type of torque numbers you guys are making with the EJ257/VF48??

270HP on a mainline is about par for the course for a VF48. Do you know your MAF g/s ?

I made 350 ft lbs on my VF48 on a DynoJet. Theres no way you're actually making 680 NM(501 ft/lbs) on a stock block and VF48, something wasn't reading correctly.
