i know this is kinda old school tech here but i'm not cool enough to have a LXX engine yet......i have a Tpi maf setup off of a '86 camaro on a 5.7 285hp gm crate engine, it actually runs very sweet but i have been thinking that i would like to get a little more hp out of it.  i have read that tpi doesn't really like aftermarket cams too much so i wasn't really looking at that.  was just wondering if it would be worth it to put the $ into a bigger throttle body, adjustable fuel pressure regulater and some bigger fuel injectors and a performance chip.  or should i just be happy with it as is and save my money for a 6.0?
