Default Should I install a ported throttle body

I have installed the borla exhaust, and the afe air intake, and I have a solar 91m throttle body that's not installed yet. Is it a waste putting the solar throttle body on if I'm not doing a ported manifold intake?

Short answer yes,
i've had 95mm soler installed and removed because itade the car jerking/ hesitate (my english is not good sorry) when accelrating from zero.reasons:-
not matched witha ported head and most importantly it needs a tune other wise more or less no point.

My two cents is don't put it on. I had a ported TB on and I didn't notice any difference. It ran great, very smooth, but honestly compared to stock I was trying to tell myself that it was better but I know it wasn't. A Throttle Controller is a MUCH more impressive mod than a throttle body.

Short version, all porting does on a TB, is allow air flow faster with less throttle vain opening, but it really does screw with the complete throttle body van range in regards to be proportional (flat spots withing in the over all range of the vain opened portion rate)..

So may get a slight bit more zip with less peddle push since should slightly better there, but deeper in the pedal push when trying to control the back end out of corner on road couse, where thing can get a bit dicey instead.
Don't believe me, bench flow the TB for vane open percentage verses actual flow, and going to be a eye opener (why none of the ported TB will come with a flow verse vain open percentage graph in the first place).

You have the AFE CAI, go with matching your Soler throttle body with a ported manifold or the even better the Carbon pTM manifold. Contact Mike at Soler, he will likely recommend swapping out your Soler 91mm with their LT5 95 mm and adding their very well appreciated C8 Soler Throttle Controller. This setup will bring out the very best of your AFE CAI and Borla exhaust. Read up on the C8 Soler Throttle Controller, probably the best mod for the C8 at a remarkably low price.

No it does nothing without changing the size of the intake manifold.

The C8 Soler Throttle Controller has 37 settings including oem and not a better TC on the market. I have the non-wireless version, not saying it's better, just like not always relying on the internet. The oem C8 throttle response is intentionally GM attorney non responsive.

Contact Corvette Forum Supported Vendor Mike at Soler. Let Mike recommend your best Soler 91mm options! I think your set with the 91mm TB and the Soler Throttle Controller together, however Mike knows best.

Pictured is my LT2 Carbon pTR Intake Manifold matched with a Soler LT5 95mm Plus Port Throttle Body.

I don't know what you are talking about with "flat spots". Soler bench flow tested every single ported throttle body on the market at their facility and released the results in a YouTube video like 4 months ago. They show the flow at every 10% increment of opening and you can compare it to the OEM numbers that they tested...
All of them essentially perform as OEM did as far as having a particular ramp up in flow with a higher opening %. Flat spots wouldn't even be possible if they make the opening larger with porting then every throttle opening percentage would have the same or very similar increase in area for more air...

I had thee same issue when I installed mine. However the ECU relearned quickly. Less than a week or so of driving, it’s super smooth. I honestly forget about the mod most of the times.

I had one left over from my C7, so decided to install it on my HTC (royal PITA).

I had a solar TB on my 2016 and it made a noticable change in the off idle acceleration - much better taking off at the traffic light.

the LT2 and LT1 have different intake manifold. While on the LT1, it made an instant noticeable difference, not so much on the LT2.

I think you should preface your statement by specifying which throttle body you are talking about from your experience. Porting has changed a lot in the past 4-5 years and brands like Soler have multiple options...
Other people may have a different experience on the LT2 platform because they installed a different TB...

If you're looking for a ported intake manifold, I have a ported Gwatney manifold for sale.
