or you will detonate for sure, especially without intercoolers to cool down your charge. The most you can do with stock injectors and intercoolers, on a cool day, on pump gas, with a little octane booster is 17psi. You might be able to get away with 19psi, with some race gas 100+ ocatane and nice cool day. Btw, you don't need a boost cut with a boost controller. Throwing NOS into this whole equation will mess things up more because your injectors are too small. Can't run close to mid 12's even with that kind of setup. You would need slicks to hit high to mid 12's at best with your setup. I've flash boosted to 21psi many times before but I wouldn't recommend it. I have a vacuum leak somewhere which is why, I flash boost sometimes when I'm not paying attnetion. Gotta get it fixed soon but I haven't had a chance obviously. -jeff
