Delay Acceleration help
just installed injen cold air intakes and ISR test pipes on my car
when flooring the pedal. There's a slight jerk or power loss then all the power comes back and pulls hard.
Usually happens around 2100-2300 or 3000 if I punch it there.
Just seems to pull slowly for a brief second. Then pull hard after.
Anyone know what could cause this?

So it's normal for it to be jerky after hard acceleration? I went full throttle in 2nd.
2100-2400 jerky delay acel
everything above was good
then 4100ish-4300 it did it again
imma double check all clamls hoses and probably clean the MAFs

I'll shine in since I made similar mods. I have an 07 Nismo with 53k miles. Installed an injen intake, HFC, and Tanabe y pipe. The ECU is seeing a lot more air... Don't be surprised it's running on the leaner side. Car needs to get tuned. I experience the same thing. Putting it into the relearn modes helped a bit. Easiest way is just pull the battery for 30 minutes and put it back on... Drive it around a bit.

I'll go ahead and disconnect my battery overnight although I did have the battery disconnected prior to installing the intakes. But not the test pipes.

I have the same problem installed my injen intakes an testpipes two weeks ago an now agency power exhaust an mine does that I have been told that I need a tune an sometimes mine will idle at 1,500 rpm for 3 seconds after I have done let of the gas when coming to a stop, I have got my uprev license an cable tuner in today now I just gotta wait to get another 300$ to pay a guy I know to tune it if it fixes it I will post back but it will probably be a week before I get it tuned
Also I have done all the little tricks unplug battery for 2 days an the throttle relearn an check for vacuum leak didn't get any luck so I'm assuming I just need a tune
