I have an AMS intake and I was using the cobb stage 1 91 octane map, little did i know.. I use 93.. so ive technically been running the wrong map.. now that I have the correct map.. after i upload it to my car will I notice it even more?

anyone?? bump

Maybe a little, I would just pull the pill and put the damn stage 2 map on and then you will notice a lot.

im confused.. cobb said i MUST have a TBE or atleast a CBE to stage 2..

I wouldn't do their stage 2 until you get the CBE/TBE. They're obviously shooting for safety, but I'd at least get CBE+test pipe on before doing Stage 2; I doubt the downpipe really makes a difference.

Of course, it might, and you might explode, so, yeah, your call :p

You can run the stage 2 without any issues, look at both of the maps in ATR, there isn't anything in there that will make your car explode, that is just being silly. LOL

Fair enough. I just think it sort of defeats the purpose of Cobb's stages if you just jump to stage 2 right off the bat. I'm glad it works, but it just seems counter intuitive, if their hard work and effort in making the best map for your mods can just be, ya know, ignored :p

im sooo lost. i kinda done have a clue as to what im doing..

so currently im running stage 1.. so a stage 2 gives you more power but i need to take out my boost pill 1st? is this easy? and what do i look for when running a stage 2 to see if everything is ok.

They also tell you do run a cat too, and we all know how many of us don't do that!!!!

Just log knock, which should be in check. Some will agrue that the increase in exhaust gases will harm this or that, hince the reason for the TBE but the stock exhaust isn't that restrictive, shit it is built for a turbo car.

Just follow there instructions for boost pill removal, takes about 5 mins.

so remove the pill and put which stage 2 on?

93 octane if you run that fuel and for the AMS intake. And just so you know all of the intake maps, the only thing that is changed between them all is MAF scaling so you don't overboost.

two tuners in my area (one being cobb plano) advised a HFC/Test pipe, and a cat back before going to stg2. They also advised a wideband and blue relay upgrade to go along with it. Everyone I've talked to have said that the stock downpipe is fine. I've also received the same advice here on the forum.

On the other hand I've read there are plenty of people running stg2 on the stock exhaust without any problems at all, so it's your call. If you do it, log a lot to make sure everything looks ok.

I was told by Cobb that I couldn't run a Stage 2 map with testpipe back...I needed downpipe back in order for it to work correctly.

They do say that. But... many of us did it with 0 issues.

I ran stage 2 on my GSR for 7k miles with testpipe and CBE with ZERO issues, stock downpipe too, when I added the UR/o2 downpipe, that is when I had problems, hugh overboost, like 30+ psi, so I had to get it pro tuned, cuz it was driving me nuts. LOL

Can I run stage 2 with my mods + a test pipe. I have to remove the boost pill to do stage 2 correct?

So here is the deal straight from the guy who made those maps.
They are all made for use with the stock cat and thats how they were calibrated.
They say to use a TBE in the notes but they also consider the Cobb doughnut back down pipe with a stock cat and generic cat back TBE. In all reality the stock DP can flow quite a bit and most of the tuners will tell you that with the stock turbo its plenty really so just throw the DP out of the equasion for the stock turbo.

The main reason they tell people to run a Stage 1 vs 2 is because if you do any sort of track racing the EGT's have potential of getting very high and causing knock. SO basically on the stock cat back and running hard at the track you may get some knock if your keeping in the throttle for long periods of time.

Now since Cobb hasn't seen all of the logs from people using the different parts and configurations on their cars its really hard to blanket whats good and bad for all of them. Personally I have seen so many logs from people on here I can tell you running stage 1 vs stage 2 when you have more mods is far more harmful to your car.

The MIVEC mapping on a stage 1 is way more aggressive than the stage 2 so if your running a test pipe and pretty open exhaust you will boost spike like a mother fucker faster. Personally I find that the stage 2 is safer to run in most cases because of the differences in timing and MIVEC.

If you have a HFC or test pipe I would run a stage 2, if your running the stock cat with stock exhaust give stage 1 a shot but watch your knock. Also I think a lot of people have a misconception of what the pill does. Its just a restriction in line to hold more boost. Cobb has you pull it because it allows the pressure to bleed off faster and allow for faster boost correction.

Thanks Hollywood.

There are so many muffler variations, that some TBE set-ups probably have more restriction than a very high-flowing CBE. If your TBE system is running a large muffler and is fairly quiet, then I'd be willing to bet it's more restrictive than a CBE system utilizing a small (or no) resonator.

On a grand note....i see COBB now supports my 2009 MR!!

could this be the same reason im having boost spike to 27 psi having a hfc, cbe boost pill in using stage 2? thanks

Ok so ill install my tp and load stage 2. Another thing how is stage 2 compared to 1? I've been on stage 1 for about a week now and I'm loving it. Is stage 2 even a bigger jump?

Depends on what you mean by boost spike. If your in 3rd or 4th and you go WOT from 2000rpm whats the max boost you reach? Because thats the boost number the map notes refer to, not the occasional 27-28 spike you see for a fraction of a second because you jumped back on the throttle in 3rd gear at 3500rpm.

Yeah feels pretty good, go out try it and monitor knock. Monitor it for stage 1 then do the same for 2.
