Hey everyone.

I installed a hellion twin turbo kit on my 2016.

Going to try and tune it and the MAF readings are coming out lower then stock.

Just seeing if anyone has run into an issue like this with this kit or any other turbo kit.

Also a boost leak test has been done twice. She is making a solid 7psi.

Thanks in advance!

They make new pistons every day, so why worry?

Is this a blow through or draw through MAF? In know in the coyote blower applications I use the stock sensor in a blow through 4" housing. I also use a honeycomb before the MAF to straighten the air for a better signal. 11psi and 676rwhp and zero issues.

Good question. All I know is every other person with this kit I have talked to used the stock MAF with no issue. Lol so I am not sure

Was the harness cut and spliced at all or is it stock length? I've also seen poor solder connections give issues when harnesses are extended.
Have you tried to call Urist to see what there take is on this?

Stock length. No cutting or extending needed.

I have called hellion twice and 1 other shop with no luck. They keep saying boost leak but I have verified multiple times there is no leak.

I was only asking because I'm not sure how you would test that.

Oh no worries.

Basically remove both air filters. Put a special cap on one turbo to block it off and then a cap on 2nd turbo with a fitting to allow you to use air compressor to pressurize system.

Turned up to 25psi and it held no issues
