Well after thinking about it for a while , I decided to build a Regrounding setup ... Got 2 Streetwire Battery clamps , new big wire , did the + like it was , just new terminals , and made new grounds using big ground cable , Battery to body to engine , and added a distribution block to add new grounds to the intake manifold and Air flow sensor ..... let me tell you !!!! Way smoother , and it does pull harder , I have to say its one of the most quickly noticeable mods I have done so far !!!! I was blown away .... I had doubts about it actually doing anything , but I am sold !!! Get those grounds clean and tight and add new grounds to your MAF and Intake and you will not regret it !!!! Next is the truck !!
