Dont mean to hijack but first off thanks for the info. I spun a bearing in my 98 gtp and got a replacement l67 in place. Well come to find out it had 19lb injectors on a sc fuel rail which leads me to believe its a n/a engine that has been top swapped. So i put my 36lb injectors on and my old fuel rail on it but if it is a n/a bottom end with higher compression my pcm will work fine? I will be watching the kr and thing elsr I should keep an eye on?
