I don't know that you would make any. You need to be FBO to run the Stage 2 and see expected results. I think you would need an intercooler, and exhaust as well.

You can run stage 2 (not stage 2+) with catless downpipes. Edit- I cant find any dyno's with your setup. Doesnt really matter though, just try both and 1) see how they feel and 2) compare logs.

Wrong. DP's are only requirement for Stage 2. See first post of this thread!

Hardware Requirements
Please see the hardware requirements for these Stage2 and Stage2+FMIC maps below:

Stage2 – Intended for vehicles equipped for the following hardware:

• Requires upgraded high-flow downpipes (catted or catless are acceptable)
• Upgraded cat-back exhaust system recommended, but not required
  
• Upgraded intake system (DCI, panel filter or otherwise) recommended, but not required
  

Stage2+FMIC – Intended for vehicles equipped for the following hardware:

• Requires upgraded front-mount intercooler (FMIC)
• Requires upgraded downpipes (catted or catless are acceptable)
• Requires Upgraded intake system (DCI, panel filter or otherwise)
• Upgraded cat-back exhaust system recommended, but not required

Shouldn't there still be a significant bump from stage 1 for just adding DP's (without the other mods that are only recommended in stage 2)? Of the 50 or so WHP increase from Stage 1 to 2+ (assuming required mods only, so no cat back exhaust, which is how their test car was), I'd have thought/hoped 30 WHP would be from DP's, the rest from the other mods.

Any guesses anyone, until Cobb provides a Stage 2 dyno?

check out the first post. There's a few dyno's comparing stage 2 and stage 2+

[xclone]

I just dyno'ed today on a 535 and saw little to no gain from stage 1 to stage 2 (no fmic though) with catted DP's (AR). I talked with Cobb and they confirmed that going from Stg1 aggressive to Stg2 Aggressive with only DP's wont show much gain because you are at the max load of the IC.

So, in other words, if you want to go to stg2, plan on getting both your IC and DP's upgraded to make it worth it.

[Z3->WRX->335]

I talked to one of their tech support guys the other day about stage 2. He said DP's are the only thing that is technically required, he said they highly recomend a DCI though. He said the catback was only required if you have a 135. He said when you upgrade the FMIC and go stage 2+ you will really see impressive gains.

I've always wondered about this...maybe someone can explain it to me. Why does the FMIC have such a large impact on the car's performance if it has a tune? I mean I am aware (I think) that when you are pushing the hell out of the car for an extended period of time, and the oil temps go up, the tune will be less aggressive to be gentle on the engine. But for a daily driver, who does not push the car much except for on-ramps and at traffic lights, how does the FMIC help? When you are not pushing the car, the temps are "normal", no? And with the temps normal, why would there be a difference in power delivery between OEM and aftermarket FMIC???

[mithiral67]

Because the stock fmic sucks and can heat up significantly even on one simple quarter mile run. If after one run your intake temps shoot up to 150+ the chance of detonation and poor performance increase.

An aftermarket fmic, does wonders to keep intake temps down.

But I just want to have the power occasionally, not constantly. I don't track or even race but let's say you are doing your first run on the track, is the power delivery going to be different because you have an upgraded FMIC?

Yes, intake air temp is a big deal to how much power you can safely get out. I think you are misunderstanding what a piece of junk the stock intercooler is. It is a worthless piece of you know what. Wait until you take it out and compare it to an upgraded one. The IAT's are much better with an upgraded intercooler.

[kaigoss69]

OK I am an idiot! I thought the FMIC was an oil cooler, but it is actually an air cooler...

I feel stupid now. I should go back to the audio forum where I (usually) won't make an ass out of myself.

[Z3->WRX->335]

The difference is probably going to be more from the more agressive tune they are able to map because of the benifits from the intercooler. I don't know how much of a difference you would feel with stage 2 with an intercooler, but I would assume not as much as stage 2+, which is not possible/safe without one.

No worries. The stock oil cooler is fine for street use.

Haha, how can you expect to see Stage 2+ results with a Stage 2 setup? With a stage 2 setup, I only expect stage 2 results.

If you expect to see Stage 2+ results, then you'll need the required mods, which means being FBO!

Wierd. I was sure I thought that on these forums until now, people had good gains from adding a DP, but maybe that's after they had already installed a FMIC.

On the 535, the tech did tell me its exhaust is more limiting than the 335's for sure, so maybe that's part of the problem.

I don't believe the testing that was done was accurate. To properly test the gain from stage 1 to 2, you should just add DP's and have no other supporting mods (the recommended ones) to see the impact of DP's. Then to see the increase to Stage 2+, add the other required mods.

The car that they ran 2+ on had DP's, but a stock intercooler, which is required for stage 2+. So what's the point of running the car on 2+ maps, with a stock intercooler? You're not going to get much in gains over stage 2 obviously.

Quote from Mike's post: "Since last round I've added CPE downpipes and an OEM N55 midpipe to the car. It's still running the stock intercooler and 135i muffler back, still on 93 octane, etc. "

I've got a running log going on another forum that I'm trying to keep updated with Dyno and Cobb logs to show what I am seeing from each mod/step I take. The Ic should, probably, be the last mod as I don;t want to get into meth integration. My car is a daily driver so I don't want to tune the piss out of it, just make it really embarrassing for a stock 335 to try and "show off" beside (no offense to the 3 guys). Getting beat by a 4 dr sedan iwth two kids seats in the back (without kids of course) will be a nice laugh for me.

i may have to call Cobb since i haven't seen them on the forum much this week, but curious how far along the additional throttle mappings are coming for the Stg2+ FMIC Agressive maps. i was planning on running MS109 at an upcoming drag event.....and was hoping for a really agressive map that could take advantage of it. guess it would be similar to the meth map that Rob is working on?

I asked that very question yesterday. The answer I got, and I will quote this, was: "We do not have any additional throttle maps for Stage 2, yet".

No timeline obviously but I got the hint.

oh ok...thanks xclone.

Cobb been pretty quite lately, any news on throttle maps?
