I have a Cobb Accessport with a custom tune on my GTR. I love it!

Incredibly easy to install, user friendly interface, and the results are fantastic.

If this was available when I had my 335, it would be my tune of choice

Thanks guys

bone stock you mean only with v5? no dci ? and same with cobbs car only with cobbs tune and no dci? if yes okay 5 whp from cobbs not big deal as i say its very similar....wonder how those cars will perfom in a street

Your confusing everything he is saying.

He is saying the different between SAE and STD correction on the dyno is only about 5 WHP.

He is also saying the car has no DCI on the cobb vehicle.

Theres really no reason the cobb cant get the same HP as piggys or better.

Can you explain what makes it better? These runs are easily manipulated, you could have run 91 on the other tunes, conditions could have been diff. Where was everything tested...same place? Was it same octane? Same dyno? Same day? same car? Same psi? Come on be more specific. making claims like that cannot be compared unless you give all of that info. Im not trying to bash, but dont make claims unless all factors were the same. You need to list EVERYTHING. BTW many manufacturers/vendors use STD because it shows the most favorable numbers. If I were you I would use SAE bc number manipulation only gets you a bed reputation around here. Just my opinion. Until you have a car producing more total whp and tq and produce faster times than the piggybacks, I would refrain from saying the COBB is better. It might be your theory or hypothesis , but until you have the facts/numbers...don't make such claims.

Uncorrected FTW.

lol ok here you go(i know you were kidding) on 100 octane, Mach V's dynojet

Theres another showing both runs and the rpm

The reason car manufacturers dont run open air intakes is quite simple really.

A) A close box chambered intake reduces noise (95% of the avg joe doesnt want to hear their intake noises).

B) Open air intakes get dirty faster, increasing maintenance cost (the majority of drivers wouldn't want the hassle of cleaning their open air filters or replacing them at their high cost)

C) Open air intakes allow for potential water to enter the engine easier, depending on location obviously ( you wouldnt expect your grandma to start avoiding puddles in such in the rain to avoid hydro-lock ETC)

Those are the reason manufacturers dont run open element intakes.....

They designed their intakes for noise reduction, practicality, noise reduction, and consistency in all elements and temperatures etc

We are the small majority in this world that wants to hear our cars make noise, want to find that extra power, and will tolerate the risks and rewards going this route. Including any extra costs along the way.

I really want to get this thread back on topic.

Its kind of funny when people claim BMW wouldnt do XYZ blah blah, except why did they fit this car with mickey mouse HPFP?

If you dont believe me, Just PM and tell me. We can talk there . <--- this is for the grammar police on typos

This quote is too funny to be left ignored.

Someone probably didn't care for Verb's callout thread.

Elaborate? this makes no sesne.

Vendors use this higher number(STD) bc it makes their product look better, period. If one chooses not to list the conditions and specs it makes it difficult to judge the validity of the run. I dont care about your comments from the peanut gallery. Dont chime in if you dont have anything useful to show or say.

[Enicinitas]

To all the noobs (myself included), there are a few people on this and other boards that I would think twice about arguing with: clap135, jpslick, myst, cbr335, and, mr.5.

I've learned alot from reading there posts - of course there are others, certain sponsors... These guys may come across as inflammatory, but, they know and have tested this platform extensively. Just friendly advice

STD measurements are almost worthless- nobody uses them except for dyno queens. Without elevation/temperature corrections, you can't accurately compare mods or cars unless the dyno pulls were made on the exact same dyno at the exact same time.

None of your post makes much sense.

Actually nothing you said makes sense...

I said they equipped the car with a mickey mouse HPFP... meaning its a piece of crap. That makes perfect sense to me considering the amount of failures and current recalls.

And PS smarty pants there is a low pressure fuel pump on this car too.

Thank you, that was useful and to the point. Thats exactly what I was saying.

This is what should have been used. Same run as posted above but on SAE.

I like reading their reviews and experiences too but some of us have been through this before or have equivalent experience on other platforms/cars.

Are the features of the AP only a benefit to the end user or with it give you more flexibility with the tuning? I know Doug's custom tuned N54's are worlds smoother than the piggybacks. Will you only be tuning with the AP in the future?

I'm not calling you or anyone else in particular a noob. I'm glad that you have posted your COBB experiences lately. I too am very interested in what Cobb is going to end up bringing to the table.

Fwiw, I have run jb3, v4, and giac st2/ plus. It's a hobby... And thanks for pointing out 'their'. Yes, I have a education as well, I'm not into proof reading my phone though.

Just add 2.6% to your SAE numbers to get STD and subtract 2.6% from the OP's numbers to get his SAE numbers. STD is calculated just like SAE and is a fixed figure just using higher ratios.

[BobS]

Nice numbers. I can't wait to see what Cobb does with Stg 2. I really like the handheld ability and flashing at home.
