First couple of pulls after BLT, what do you guys think?

How do you tweak the tune to get the turbo to spool quicker? Im having issues with peak timing just at 13ish around 17 psi of boost on a TO4s GT35 hybrid turbo. I tried increasing the boost to 25 but then I run into knock around 4500+. If I use timing to get rid of knock then I end up with very little timing up top (maybe 4 or 5) Any suggestions?

Yeah, stop using pump gas and upgrade to a better fuel. Pump has its limits, and you're probably beginning to see them. Small turbine + high boost + timing advance + pump gas = knock.

Post a 3rd gear pull and I can look at your spool up.
