Car bogging down randomly

[19984V]

Lately it seems my car has turned into a moody b#$%.

Its been bogging down a very random times.

When it starts if i get on it pretty hard i can feel the "bog" leave and it will pull again like normal.

Let me describe the bog; its not a misfire and the car sounds fine at WOT, but i feel an extreme loss of power. It seems to be only top end as well, bottom end it feels about the same. (shitty with imrc deletes :bored: )

Sometimes i cant work the bog out.

Any idea what this is, and WHY its happening?

Edit: I feel the bog it seems pretty consistently after EVERY time i spray. ( But randomly with NA )

I want it gone -.-

Also: on a more technical level - The bog comes and goes with my NA tune, as well as my nitrous tune with 6 degrees retard.


Thanks

My first guess would be the fuel pump, but you need to data log and catch the numbers when it bogs. I would stay N/A until you find the problem.

+1 on the fuel pump. When was the fuel filter changed last and did you get a tune for the IMRC deletes?

Check your fuel solenoid for sticking or leakage into the line.. could be making you run rich at times, especially after spraying the car. I had a similar problem once that was my own doing.. I had tripped my master arm switch but the bottle was off, leaving me with a nice fat fuel shot at WOT.

Fuel Pump about 10k ago.

Yes my car is tuned for the IMRC deletes.

With it being a fuel pump, wouldnt that affect the actual shot as well? Not just the after shot.
