ya where did he get that, I mean set your boost controller to 0 and see what happens to your hp and torque, obviously it dont increase torque, LOL

 

with 93 octane (without meth) you can run about 23 psi safely. I run about 23.5 but keep a close eye on it. Your timing at peak torque 4000-4500 will be about 4-5* ramping up to 14-16* at redline. So I would say a combination of both but excessive timing will only end up giving you high knock counts and you wont make as much power as having the right amount for your engine. Spooling lean (12.5 or so) will make good peak torque, after peak torque richen to 11.1 and ramp timing up till redline. Good luck and happy tuning!

 

i love when people say this.... when ur drag racing you're over 5500 the whole time anyway....

I set at 30psi but after 5k i never see that much anyway... rpms never drop below 5500 i see 27 anyway and a minimum of 23.5 pounds. So it really wouldnt matter if i was running 40 pounds on my stock turbo, its only gonna run what it can run.
