I need to know if i need a tune. 07 SS/SC With current mods: 1.Magnaflow CB,2.XTC DWNPIPE/W/Hi flow cat, 3.and KN typhoon cai. Do i need to run a smaller gapped plug and do i need a tune to see potential from opening up the car?

 

plugs are fine, a tune would benefit you

 

ya its like you can but you dont. if you were stage 1-2-3-100 lol then yes!!!!!

 

Thanks for the help guy's, i just want her to run at her best! I want the car to breathe first, then i will add a stage kit, heat exchanger,torque dmpner ,and then next yr harrop! Damn i love these cars! Happy Modding!LOL
