stop using those octane boosters, sometimes they create deposits on the plugs. Your problem sound like its a misfire, if you hear popping then its misfire. A timing retard is almost not noticable, in other words it will feel less powerful but not a dip at a certain rpm. Also, you may have water in the tank. Change that pump asap, its cheap insurance . Laterz slowboy, lol,lol.

Timing retards are noticeable... if you have a good feel for your car... but of course, if you dont.. your car can hit a brick wall and you wouldnt know

I found the problem. Ever since I got the coilpacks replaced by the dealer, I have been getting misfiring codes. I know that you mentioned that you got it once in awhile, but I was getting it nearly everyday. So while getting ready to check the plugs, and do a leakdown just to make sure everything was ok, my friend milton brought by his voltmeter, and we checked the coilpacks resistance. Stock according to the Mitsu FSM should be anywhere from 8.5-11.5. One coilpack was showing a resistance of 12.5. And the other was showing was 14.5.
It appears like I wasnt getting the proper spark therefore running way too rich, and getting a bad misfire.

So what is your take on the situation then? I changed my plugs and made sure they are gapped properly, and I STILL get the bogging. So the plugs are out of the question.

if you already swapped plugs, new tank of gas, then your problem could very well be the stock gas pump is not flowing enough fuel. Maybe because of the colder weather your car is requiring a bit more fuel and therefore causing a fuel flow concern. Try this, go out and drive your car on the highway off boost at those same rpms that are giving you problems. If it drives perfect then your problem may very well be fuel flow. Throw Sam's pump in there. By the way, did he get the cams installed already?

Probably changing the fuel pump would solve the problem.. but the problem was not the fuel pump in the 1st place.. the problem was over agressive tuning that is not suited for the fuel pump... how about this... ask al or shiv or whoever it is who tuned your car to tune your car to 600 hp... then change the parts to suit the tune... doh....

Resistance does not fluctuate at random
As heat rises so does resistance (the way thermistors work)
So if his Coil pack is showing 14.5 ohms resistance with the car cold and spec is 8.5 to 11.5 that means that it will go higher during normal operating temperature and WOT temperatures .

do you even know how a fuel pump works?
what would a retune have to do with his fuel pump?
people bashing a product that they dont even fully understand

How a fuel pump works? Errr... it pumps fuel? Doh!
How a fuel regulator works? Err... its regulates fuel? Doh!
Bashing? Errr... Doh!
