Im getting some long tube headers for my camaro and im wondering if this will have any effect on my tune which is just a basic tune from speed inc? Itll be headers with y-pipe. I currently have an slp y pipe with no 02s

 

Yes LT headers changed my A/F ratio and had to be re-tuned to get max RWHP after the install. I had to lean my A/F ratio (WOT) after the install.

 

yeah but one kinda tune and set up we talking here. This is just a basic tune from speed inc that mostly revolves around shift points, Torque management and what not. I dont have any bolt ons or anything crazy that require much attention to air/fuel.

 

When you get Lt 's you might wanna get a retune is what he is telling you.
