I'd like to know what mods I should do , I have done 3" exhaust and performance cat and mufflers , intake , that's about it. I was thinking tuning pcm but not sure.... best tune for it also? Have kids so money isn't very much for things like this but I find ways to slowly purchase. I bought the car for a good price so I didn't have to drive my diesel everywhere all the time! I want power comparable to my souped up f250 but I know that's probably many mods but you guys let me know if you don't mind what to start with and what the gains are as well as price! I appreciate all your input a lot. Also is water /meth a good investment for my gtp cu I can make a kit from parts I have at home and a washer pump ... thanks
