Default New intake. Now very slow

Hey guys,
Just got my s&b and installed it yesterday.
With it im noticing it has a TON of turbo lag.
It is taking twice as long for the turbo to kick on from a dead stop. Is this normal. or did i hook somehting up wrong? (dont know how thast would happen)

Definetly not normal, did you hook up the maf sensor? Maybe damage it while putting it in? Hopefully nothing went into the turbo .

if it is an oiled filter you need to clean your maf sensor

clened my MAF. And no change Everything is hooked up fine. no leaks.

Once the truck is moving it seems fine. It is just getting up to speed is a problem.

I might get a new MAF. the top of mine was cracked when i bought the truck

MAf's are expensive, see if you can pull a code from it

I would put the old intake on and see what happens. But most likely your maf sensor
