DITCH THAT SUPERCHIP AND GO WITH A NELSON TUNE FROM NELSON PERFORMANCE, ALLEN WILL SET YOU UP.
That looks like an interesting idea of modifications for the Sierra. Well, my uncle is also planning to do some modifications of his Sierra to increase it's performance. At first, he was having a thought of getting a superchip but having read what Jamest said, it's better to hook up a nelson tune. Anyway, I'm gonna let my uncle know about this so he could check it out. Thanks for sharing some suggestions.
