NOS is cheap but kinda risky, and expensive and very risky if you use it a lot. If you want 25hp constant power from your SVT, a chip won't do it without more mods than you have, but with a couple little tweaks and THEN a chip, you could get 25. BUT, that would be a pain in the neck. So I would say that you're looking at something like a turbo, which is expensive but not a huge pain for you, if you have it put in, or, a ton of little mods, which is not easy, like Demon has, but done right can be very sweet. Also, the 3L is a bit of a pain in the neck, I've done 2.5 to 2.5 swaps, and even that is pricy, but it would be chaper than the turbo, and it's a great place to go before modding up.
