I have a 7675 on my truck spool is very fast but I'm also tapped out at like 650-700 hp with E85. I wish I would have done an 80+ now.

How'd you get the turbo to light of QUICK ? Did it take some fine tuning to get the SPOOL you wanted ?
Care to show screenshot of your spark timing table ?
What torque converter are you using ?

. Thank you.

Fully forged 5.3, Circle D Triple Disk 3400 Stall, LS1 Heads with valve job, BTR Stage 2 cam, custom cold side and exhaust. My build thread is on here few post below if you wanna look at it. I'm on 17lbs at 19 degrees so semi-conservative about to turn it the rest of the way up to 20lbs and I should be mid to high 700s.

Are you running straight methanol ?
