I think it's an issue with the tune. That's why I'm here. I'm only having the issue when the car is tuned, whether I have the stock airbox in or the PRL intake in.

The PRL HVI is CARB approved.

So I took out the PRL HVI and put the stock airbox back in. Tuned it, took it for a spin, and it's still bogging.

High volume Intake plus tune = issue
High volume intake plus tune and traction control off = issue
Stock airbox plus tune = issue, and slower
High volume intake with no tune = no issue ...

If you are using a CARB FlashPro you will not be able to use any intakes that require special tuning as they should be designed to run properly on a stock vehicle. The CARB FlashPro cannot make changes that alter emissions.


The PRL site says that the HVI doesn't require tuning because it comes ...

the prl intake flows much better than stock, i had to try each of the CAI calibrations till i found one that did not put the car in limp mode at 4000-5000 rpm, i dont remember exactly which one worked for the prl, i can pull the calibration and let you know in a day or 2.


How do you account for ...

It could be that, please try it and see.


I don't know if you saw my post, but I disabled traction control. It was better, but still bogged.
I spoke to a tuner and he suggested that the car is running too rich or too lean with the tune. He suggested taking out the PRL HVI and putting the stock ...

I do have the CARB Flashpro

Also, when I am doing a new calibration, it gives 8 options; the 2nd option is 240 lb-ft tune and the 3rd option is CARB pending 240 lb-ft tune. I have tried both, but I was wondering if they are the same or if I am supposed to be picking one in particular.

I disabled traction control, tuned it, and took it for a spin. 2nd gear felt better...it pulled and felt smooth. It bogged a little in 3rd. I read that disabling traction control by just pushing the button doesn't fully disable it, so I tried the method where you push the button off and on while ...

I haven't tried that. Did you see something that indicates that might be the problem?

Ok, I think I did this right. I uploaded a new calibration and was able to replicate the problem. On the first datalog, it bogged right after shifting to 3rd gear. On the second datalog, it was right after shifting into 2nd.

With your FlashPro connected to your computer (the FlashPro can be, but doesn't need to be connected to the vehicle for this), from the FlashPro Manager software, click the "FlashPro" button in the toolbar. This should pop up the "FlashPro" window. On the Flashpro window, click the "Calibrations ...

Sorry, I'm new to the world of tuning and trying to figure it out

Then I'm missing something, because I thought you just select 240 or 250 and that's it. I didn't know there was anything else

I hope I did this right. I attached the datalog. The calibration was the CARB 240.
