Default Tuning EBC on a 1.6L GT2871R

thought I'd post this log, for those who are curious how a GT2871R can spool on a 1.6L with a .02" overbore.

log manifold, 3" turbo back, 8.5:1 CR, stock head.

more likely roughly 4.4K it hits 15psi. not too shabby for a massive torque attack.

I was asking because I was looking at a 2871 myself and am worried about spool on the .86 A/R. I know that Begi uses a GT28RS with the larger hotside on their kits. I was fortunate to pick up my MSM for a good price and am using the money I saved on de-MSMing it . I have the .86 A/R spec'd now, but I am wondering if the spool is going to be that much worse with the bigger hotside.
