I would go with the TS chip and hold off on the exhaust. Kinda like playing possum lol. The TS chip will be just as good as any custom at this point. You can only get so much HP out of that truck. Then if you go with bigger injectors and such the TS will work well with that also, or a good custom like DP or the wild man. But I would play possum and tell him you been working on your launchs, and then SMACK his ars. Make sure he is on your passenger side. 007 him.:burnout
