I have a 2001 GT Manuel with magnaflow catback and AEM cai. Im getting 3.73 gears put in and was wondering what's the best mod with them. Shifter, Pullies, Mod chip, Plenum and Trottle body. What will get me the most power with gears?

 

I'd do the pulleys and the shifter...shifter won't add power tho...just better shifting

Save the Plenum and TB for later...
