Took the SHO once again to the track

60' times are working against you.  Are you sure the weatherstrip on the CAI is sealing against the hood?  Tracking IAT/IAT2 to see heat soak?  What tires are you running?

From what I can see its sealing good .
I'm going to get with my buddy to check the IAT .

On both runs the car had cooled down about an hr and went from the pit directly to the staging lane without any wait .

 
So I decided to go to swap the Air aid Cai and put the stock intake with kn drop in before going to the track yesterday.  Only got to run it once . Ran a 12.88 @ 106.9 MPH . Picked up 3 MPH from two weeks ago . DA was around the same.  Can't seem to break the 12.8 mark .
 
Proves that the stock intake is strong :)  How many miles on your SHO?  Octane?  May be time to try the 4X tune, and change the PTU fluid if not already done.

I currently have 72k on the clock. Using 93 octane tune . Already using 4x tune . Will be changing PTU fluid soon
 
I'm in Texas as well, seems it sucks our cars slower down here? I have 3 bar map sensor, 170 degree t-stat, & stage 4 tune from Torrie.  Took it out & ran a 8.6 @ 81 mph. All day. Mid 80's temps. Took it back in low 60's and ran an 8.5 with same mph. Wtf?  Went to 1/4 mile ran a 13.4 mid 80's. Took it back in 50 degree weather ran a 13.2 @ 104 mph.  Not sure if those are good or not but I hoped for better in the cooler weather. I still need to  datalog the car though, I don't know how much hat will help either?
 
Did you ever change your plugs?preferebly recommended are the MC-534 GAPPED bet 0.28-0.30,what rpm were you launching?remove engine cover,quarter tank of gas,and play around with tire psi,26f-28r preferably.

What octane are you running?  Do you have winter gas down in TX?  Launching at 2,000 rpm?  Does your SHO feel sluggish at any point?
