Tuner recommendations?

[aleccesarenriquez]

Hey guys,

Just need some advice on some bolt ons.

I currently just have a MBRP catback and a canned SCT tune.

I'm having TSP long tubes installed this weekend along with a ff tune.

1. I've read mixed opinions on whether I can run stock injectors. I plan on getting some 47 lb ones installed to be safe, but are they necessary? Should I just save a buck?

2. My tuner has some 18 manifolds available, with a harnesses to retain IMRCs. I've been on the fence about this. He did a really good job of pitching it and I'm failing to see the downside here. Anyone see any reason why not to do this? The only reason I can think of is that I want to become familiar with the long tubes first and then get the manifold when I get bored of the new toy feeling again. Although I'm also scared of what might happen if I wait too long.

3. Lastly, he's recommending the GT350 stock airbox (he's selling them for 200). Is that a good pairing with all the other bolt ons considered? Are the PMAS or JLT or any other CAI more effective? I live in Houston so hot air inlet temps are a thing to consider, especially since summer is around the corner.

Let me know if I can add more detail somewhere.

Thanks guys

All three can be answered with if your tuner tells you to do something, DO IT.

IMO-
I would go with the larger injectors. Stick to the FF and headers and see how you like the car as that seems to be what you decided and not what was being sold to you. What are your goals for the car?

I’m with Mark. You pay your tuner good money. Listen to what they recommend.
Some won’t care for the larger injectors until you swap IM, others might insist on it. Some may have a preference for a certain CAI etc etc.

Goals for the car? Trying to build a FBO that doesn’t break the bank. I won’t be cheap when it comes to necessary parts but if it’s a lot of money for marginal return, I’m probably not about it.

I will eventually get an IM, just a matter of when and which one.

If you're budget minded (hell, even if you aren't), the 18 manifold is proving itself to be a great choice. In most cases it's a perfect hybrid between ours and the GT350 manifold. I run the 350 manifold and have even contemplated switching to the 18 manifold. For the price compared to the 350 or the CJ manifold, you can't go wrong.

It's my understanding that you don't need injectors if you go with either headers or intake manifold. Once you go both it becomes a necessity to ensure you're starving yourself for fuel.

As for you intake, $200 is cheaper than just about any other intakes your going to find (new). Most of them are really for visual preference at this point. I'm just assuming but since the 350 intake is an OEM part, it will probably be a little quieter than others. Which, probably doesn't matter considering you won't really hear it over headers/exhaust. So this one is more a question of cosmetics. Do you want it to look OEM or do you want something shiny and painted or hydro-dipped such as JLT.

You will need 47# injectors if you add the 2018 manifold with the longtubes & flextune. Just another expense :ford: I got a used set of LU47's from a member on here for $185.00 shipped.

Don't need 47 injectors unless you have E85. If you do, yes, get injectors.

I am really happy with my tune from "Tuning by James" which is the guy that tunes Steeda's race cars.

Yeah I normally wouldn’t care about the whoosh noises but my tuner is recommending the intake in the event I get the manifold and the headers, although by themselves it isn't necessary. Does anyone know the reasoning behind that? When is an upgraded intake a must? FI applications only?

I guess this goes back to trusting my tuner.

Edit: words

Properly tuned, an intake manifold is showing gains with just about any one of them that you pick. With an air intake though, most of them (with a few exceptions) are aesthetics. That's simply because any major power difference is coming the tune and not the intake. Once your manifold is upgrades then the air intake becomes more of a "necessity" based on the simple engine dynamic (air goes and air goes out). So if you upgrade your intake without upgrading your manifold, your manifold is still a restriction (and vice-verse). It's the same reason that upgrading your cat/axle back exhaust is nothing more than noise without changing the headers.

This is why you will see a lot of people make the conscious decision to just jump in feet first with bolt-ons. Obviously budget plays a factor but at that point, you're not upgrading again. You've got your bolt-ons and you know that you need to make a legit commitment to make any further serious power (ie- Forced induction or nitrous).

Here is what I have gathered and from talking to Rob at PBD.
Stock IM, CAI, Long tubes you don't need 47lbs injectors for flex or straight E85
If you do the 18 Manifold paired with a CAI and Long tubes you will need at least the 47lbs injectors to run flex or straight E85.

I just did A Gt350 CAI and SW long tubes and a Rob Shoemaker PBD tune for 93 and E85, and was told I am fine with my stock injectors and E85. Car pulls hard, shifts great, sounds great and logs look great.

Awesome, thanks for the info man.

I think I'll just get the injectors because I WILL be getting the 18 manifold installed at some point. I'll probably decide this friday when I see my tuner, depending on if he has any in stock.
