Re: LT headers need tuning? If I install headers and then A-tap what do I want to look for? trying to decide between paying for tuning or going in on Ls1 edit with car club guys.And then hoping we can figure it out.

Re: LT headers need tuning? Ive had headers without tuning for a while and my car has been okay. I'm going to get LS1-edit pretty soon so that I can get the most out of the new cam and ported heads but most people say my car will run fine without tuning. <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" />

Re: LT headers need tuning? O.K. Here's my story. But first let me qualify this with pointing out that I'm a novice when it comes to performance mods. I installed a MTI lid, K&N filter, SLP LT headers, high-flow cats, and a Y-pipe on my stock WS6. All at once. When I test drove the car it really didn't feel quicker. I bought autotap and a MAFT. My initial reading showed that my car was running rich at WOT (LTRIM around 5% and O2's around 0.965). Based on information I found on this site, I needed to get my LRTIMS to 0% and my O2's between 0.89 and 0.90. Once I did this I found out that a friend of mine had access to a air/fuel meter. We hooked up the air/fuel meter and it read 13.8 (O2's where 0.893). This air/fuel ratio seemed a little high. So I adjusted my MAFT and the next reading was 13.2 (O2's where around 0.93). This was acceptable. The car definately is quicker. Unfortunately, I haven't had any good passes at the track or I would share that info with you. The bottom line is in my case I needed to tune the car after all my installs. Did I make the right choice by getting the MAFT instead of LS1 Edit or custom tuning? I don't know. But for know I'm content.I hope that helps! Good Luck!
