Sooo.... sure, let everyone see your dyno that proves that just a CBE provides enough extra WHP to show up repeatedly on a dyno. Or you could just search the board for early 2013 when a bunch of CBE were dyno'd and gaining practically nothing without a tune. Or read which part mfgs opted to not produce CBEs because they gain nothing without a tune on this platform either. It's the tune making the power not the CBE.

The best I've read is a 2-5 TQ (not WHP) gain in the midrange specifically with TRD USA catback due to its' tiny 2.25" midpipe that via raising EGT and improving scavenging at the expense of losing 1-2 WHP. Oh btw, I actually own a TRD CBE. You too right?

Please don't spread anecdotal butt dyno (mis)information without proof. If you have it, please post it and accept my humble apology.

I can't use e85 for the moment...

Grimmspeed intake is not supposed to be the best intake on the market right now where you can feel or you get the best Improvement vs the stock box?

Just asking because they seem to have done a lot of development on this, maybe at least it's better compare to a drop in? Anyway, I have this intake for the look, the sound and to remove the gazoo...

Am not looking for a lot of gain with this setup, I know intake and CBE are not the part who gave a lot of HP gain... Am just looking to know which tune is the best for my current setup...

I know also the TRD exhaust is probably not the best exhaust to get gain whatever an CBE can give on this car... Again it's for the sound and the quality of the part...

And yes, I know Headers will be the best mod for the money... Anyway, I will be ready for an tune if I have already the OFT.

Thanks guys!

So far, no intake has demonstrated any gain for NA. A few of the early ones have shown losses. General recommendation is to not get an intake unless you want one for cosmetic/sound reasons -- the stock one has sufficient flow and is a true CAI.

Maybe but will not loose any power with the Grimmspeed, I don't think so...

But wait, What's about the numbers they provide to us in the forum?

There is an OFT Stage 1 map specifically for the Grimmspeed intake. The only difference between it and the standard Stage 1 maps (any octane) is the MAF scaling. You will have to e-mail Shiv at OpenFlashPerformance with your make/model/transmission/CalID and desired octane level.
In my experience, there is a slight difference with LTFTs between the standard Stage 1 and GS Stage 1 which could improve fuel economy over the long run. Nothing serious though, and certainly very little, if any, hp/tq improvement between the two maps. All of your hp/tq gains and curve smoothing will be accounted for between the hardware you've installed and any Stage 1 map.

Perfect, will email Shiv in time I have already make a contact with him yesterday but I do not have my car with me a the moment...

Didn't gain much from the Grimmspeed intake with OFT FYI. I'm running e85 though so results might be a little different.

You also might want to do some research on maf scaling. My fuel trims were a bit off after putting on my Grim intake. If you do a bit of digging one of the members on here posted his 91 tune with the Grim intake after he did a bit of Maf scaling. I have it some where. I'll post it up if i can find it.

The OFT Stage 1 will work great with your mods.

The more you research the more your head will hurt haha.

Headers are great, just remember that if you get catless, it will smell and be very loud especially with a TRD exhaust.

If you pay close attention, nobody has given dynos comparing a tuned car versus the same tuned car with all things equal other than new intake and new MAF scale.

It is always untuned VS tuned, or untuned VS untuned, which are invalid comparisons to judge an intake's effect.

Am the one who search a lot before doing any mod... By car is based on that and run very well with all about I have done since now.

Yea I know about the headers this is why i am planning to stay stock from this side...

Thanks

Well, the untuned vs untuned comparison, which Grimmspeed posted in their announcement thread regarding their intake, is valid for the purposes of determining if the intake alone has a benefit (Grimmspeed's benefit is around 5 whp). However, I agree that there have been no reliable tuned vs tuned comparisons, which of course means that the OFT may indeed be able to compensate for the hp/tq gains through mapping alone.

To expand on what others have said in this thread, my only suggestion for those interested in this combo of hardware and mapping is that should you think you are interested in a header, save your money and do not purchase an intake. The additional hp/tq (if any) is negligible as compared to the header and mapping, particularly when considering $/whp or $/wtq spent. Without a header, I am inclined to speculate that there is a minor benefit to the GS intake, and perhaps other intakes (although I haven't researched them recently).

This simply isn't correct.

Would you please share your reasoning behind your statement?

But let me clarify - the intake has a benefit in a stock, untuned car, based on GS' dyno results. I am NOT saying that the intake definitively has, or doesn't have, a benefit in a tuned car as there haven't been tuned vs tuned comparisons. Hopefully that was clear in my prior post.
