So my car is tuned for my ls set up. i just put a b16 head on it. Ive been driving it for about 100 miles and ive taking it to about 4000 5 times or so to blow off. Now when i try to do it it bogs down and after a few seconds it comes back to normal. My plugs have been in there for about 7000 miles lol so im guesing its time for new plugs?

 

So you put in a different head on a setup that was tuned for what you had before and you expect it to run the same?

 

+1 your car need to be retuned

 

I agree the car needs a re tune on it. although it still should not be bogging that bad. I would start with Plugs then check your Map sensor just a possibility.
