BMW335i10 · 12-16-2011, 12:00 PM

y is it not possible? or i juss wont recieve full results? would i be better off getting dinan stage two? cobb stage 1 seems a lil weak

Sleeper · 12-16-2011, 12:11 PM

While you're at it, why not just run Stage 2+ and just go for it?

There's a reason Cobb says that DP's are required for Stage 2. It's not just a friendly suggestion.

Rotorocious · 12-16-2011, 12:15 PM

Do it anyway and tell us what happens

BMW335i10 · 12-16-2011, 12:15 PM

I understand they recommend it but I'm asking y.

Jeff@TopGearSolutions · 12-16-2011, 12:19 PM

Its unhealthy for your engine. Excessive exhgaust gas temperatures, combined with excessive intake air temps, makes for elevated duty cycles, increased knock and likely less power.

BQTuning · 12-16-2011, 12:20 PM

I wondered about this myself more so about the Stage 2+ as I did nott want to go cattles but high flow cats with DPs which i think they said was ok

BMW335i10 · 12-16-2011, 12:28 PM

Don't go Dinan for the tune. There are quite a few people who jumped ship from Dinan to Cobb but none have gone from Cobb to Dinan.

Rotorocious · 12-16-2011, 12:31 PM

Dinan is pretty expensive and costs extra to go up to another stage.
Cobb, buy once and each stage is free

Shellacked135i · 12-16-2011, 12:32 PM

No reason to buy Dinan when Cobb has more power on tap at a lesser cost. Follow the calibrations recommendations for octane and mods.

bryce · 12-16-2011, 12:41 PM

"stages" don't mean shit when comparing different tunes. for example, dinan stage III probably gets owned by cobb stage I aggressive 93 octane. dinan stage I is shit compared to procede aggressive stage I. etc etc etc

Fred_Boosted · 12-16-2011, 12:52 PM

DP is required. Not suggest. The intake and cat back are suggest.

How do you know stage 1 is weak without owning it? Besides, if you want serious power your going to need supporting mods anyway.

BMW335i10 · 12-16-2011, 01:54 PM

i didnt say it was weak i said it seemed weak compared to the other tunes available like jb4 and dinan stage two.. i guess ill just got with te cobb ap stage one and see wha i think....

tbtalon94 · 12-16-2011, 01:59 PM

So how does hot-rod run his times with stock downpipes?

Cobb and Vishnu PROcede are the most aggressive tunes today. You've been misled somewhere if you think Dinan or Jb4 is faster. Jb4 can likely be just as fast with a custom map. I am not trying to start a tuner war.... really, i'm not.

Methanol, Race Gas, Nitrous.... to name a few.

He did in the past, not anymore. Back then he was still on methanol too and race gas at times I think.
