theres no reason for meth at that compression. It wont do anything and you wont get response from this motor regardless with a comp that low. That comp is extremely low for this motor. A gtx2867 will produce good torque but the top end is going to fall on its face after 6k because of that compression ratio. You'll need a gtx3076 or bigger. I wish I could remember who it was on here but he was struggling to hit 400whp with that low a compression on a gtx2867r. It will be blowing a lot of hot air.
Im on the gtx2867r and ran it out of its efficiency on the top end with stock compression at 460whp on e85 at 19psi. You'll be running MUCH higher psi on 93 at that comp. Fullblown had a car on their facebook page that was 10:1 on the 2867 on 91 that made somewhere around 400 at my psi I made 460 at, and I made 40foot pounds more torque everwhere compared to that motor.
Save your money, raise the compression back up and go e85. Or you wont the have torque or throttle response youre looking for
