I did the same thing on the highway and the results were the same. Any ideas on what could cause the lag? I recently cleaned my throttle body and Mass Air Sensor to see if anything changes.

Kevin, possibly a fuel filter....? Also have you reflashed your ECU to see if it helped?

I'd suggest checking this as well. Mine was getting terrible mileage and had a little lag, so I changed the fuel filter (which turned out to be filthy) and noticed a bit improvement

OK, I will change out my fuel filter and see if it changes anything.
Eddie, I recently disconnected the negative battery to clean my TB and Mass air sensor. I also reinstalled a different tune to see if it would change anything, but no luck.

I put some more 93 octane in the tank after work and tried out the 93 custom tune. I can definitely feel a power difference between the 87 custom tune vs. 93 custom tune! The throttle response is a bit stronger and I can spin the tires easier.
Only downfall, on occasion, I am still experiencing a small lag in 2nd gear and into 3rd gear. It could possibly be the clutch...
