Who did your tune? I don't think LMS will tune for meth unless you have all the standard bolt ons...

To really take advantage of the benefits of meth you are probably going to want the DPs first... Spool sooner, runs cooler, less back pressure, etc...

Better bang for your buck will be meth. However, without the supporting mods you won't be getting full advantage of the meth.

Torrie will tune for meth without downpipes, when I was tuned by him he said that would not be an issue. SilverSH0 is correct however, there are a lot of benefits from the DPs that won't be realized with just Meth.

There are plenty of how to's on the forum for installing meth kits, I would post the links but I am on a phone. A quick search should be enough. Most people say it takes a full day of doing it yourself. Sooo 8 - 10 hours at shop rates is around 800 - 1000 to install the kits.

I'd be comfortable doing it, I just thought I remember reading something about a company only wanting to install them personally so they knew it was done right, or something to that effect.

The PPE high flow catted pipes are the only ones that don't need the rear O2's dumbed down... Which means you should be able to pass emissions with them if that is something you are worried about.

Not sure which company would require in house installation to support it...

Down pipes. If I had it to do all over again I would have gotten meth first. It feels like you tuned your tune if that makes sense. Big difference. Dp was seat of pants good but meth was awe shit good.

What I was saying is that you probably had a larger gain when you did meth injection vs someone without DPs and intake. For example, you picked up 0.15 seconds when you added the DP and then another 0.5 seconds when you added meth. If someone did meth first and then DP second, they might only gain .4 seconds with meth and .25 seconds when they did DP after (due to the DP being more of the bottleneck w/ meth only). But I would still believe one would gain more time with tune+meth than tune+DP.

No the meth was a significant difference. The downpipes weren't much bang for the buck. Tune and meth cost almost as much as dps. Way overrated in my opinion

What I'm saying is that in car mods order matters. When you did meth injection you saw a 0.5 second gain but already had tune, intake, and DPs. Someone who does meth injection with only a tune will NOT see a 0.5 second gain. It will be less due to the intake/exhaust being a bottleneck. That's why I said meth is the best bang for your buck but w/out supporting mods it's not taking full advantage of it. It will still be significant, but not 0.5 seconds.

Think about it like slapping a supercharger on 100% stock motor of a different car. You will see substantial gains from doing adding a supercharger (maybe 100 hp). However, if you have all the supporting mods already done prior to adding a supercharger you will see even more gains from the supercharger (maybe 150 hp).

Does anyone know if I buy a meth kit from a vendor other than Torrie, is the tune update from Torrie free? I've asked him this via email but he's not getting back to me.
