So last night I was driving on the highway, just entered from a ramp, and felt like driving hard. Mad sure all temps were at normal before I dropped gears...they were...I did. I stepped on it in 2nd and around 6000RPM I felt a loss in power and heard POP POP. I was like WTF. So then I shifted into 3rd, gave it gas started boosting and again around 6000RPM it poped and I felt a loss in power.

Any idea what this might be?

Thanks guys

 

Sounds like a misfire to me or maybe it's backfiring?

 

What are the spark plugs gapped to?

 

misfire?
bad spark plugs will do that?
They are only as old as this spring

well when i put them in they were gapped to .2 i believe...or maybe .25
NGK's

 

Yes, bad or improperly gapped plugs will cause random misfires, especially on boosted setups in the higher rpms. It takes 5 minutes to pull out the spark plugs. Check them and get back to us. It could also be an ignitor or ICM taking a crap on you.

 

going to try and check today.
its 80 degrees out in buffalo and being october...thats RARE!
ill take prob 1 last spin with the top down in the S2K and then check the plugs

 

not a boost guy myself, but just got done reading some posts that mentioned MAP sensors causing that issue in boosted setups. if the boost raises the Manifold Air Pressure above the threshold of the stock MAP sensor, it should give a check engine light, and cause misfiring.
