04 not as fast as it should be?

[dark04]

hey guys i have a 04 gt. this past spring i had gotten my times down to the 13.8/13.9 range since then i have gotten a diablosport predator,slp off road x and 4.10 gears. i went back last weeked and ran consistent 13.8 all night long and i was running it perfectly. it just isnt running as fast as it should.do you guys have any ideas or anything i can check thatmight be keeping it from running to its potential? also i have slp loudmouth and homemade cold air kit . thanks

Need more info. Can you list all your times? i.e. 60ft 1/8th mile. What was the elevation/tempature at the track?

Is it an auto or stick? How are you launching it, slipping the clutch, etc.

need more info to go by for a better understanding of whats going on are you spinning of the line? Do you have DR's on? and what are your times 60ft 1/8th?

Mainly, how is your trap compared to before?

I have the same mods as you in my '04 5spd plus a few more listed in my sig and ran a best 13.65 with a 2.05 60'. That is where the room for improvement is. I need traction BAYBEE!!

i went 8.81 -1/8th and 13.6 -1/4 with an xcalibrator, mac flowpath catback and a plenum/tb combo and stock gears on street tires with a 2.0 60'....

since i have added the midpipe and 3.73s my N/A times went down several tenths to 8.50-1/8th which is right around a 13.3 inb the 1.4.... given you elevation and 60' times are low, yes you should be faster...
