I got my pacesetter lt's and TSP catted Y installed yesterday. The sound is pretty incredible. All my other mod's were done at the same time and I couldn't really feel that much of a difference, not this mod, big difference in power. But Im sure all the other mod's are helping give the headers a boost. Just thought I'd share.

 

Every car is different, but it's a good chance you're gonna need a tune to get the full advantage from the LTs. Because of the LTs, your computer sees or thinks your car is running lean, so it dumps more fuel=less power.

 

Yes, I've thought about that, Im thinking of doing some underdrive pulley's and the BG Ram air. Should I wait until I get these mods on before I get a tune or would those really not matter for getting a tune?

 

If you wanna save some money and not spend a whole $550 for a dyno tune, you can get a Mass Air Flow Translator for only around $70. Its kind of like a band aid. It'll adjust your A/F ratio

 

no, the tune will not affect them...i would get a lower T'stat, or a gear to take full advantage of the money for the tune

 

It's not totally necessary to but I personally would still wait until after it's all on to get tuned.
