Omitting Data From Array Output Based on Value

I am formatting data that is stored in two arrays using foreach loops and an If Statement. I am happy with my current output; however, I am having one issue. I don't want categories with No data or - TBD - as a data value to be displayed.

Here is my current PHP:

<?php
 foreach ($finaltitle as $titlenumber => $titlename){
   foreach ($techData as $tsnumber => $tsname){
     if ($tsnumber == $titlenumber){
       $finaltsdata = "<b>".$titlename." (".$tsnumber.") "."</b>: ".$tsname."<br>";
       echo $finaltsdata;
   }
  }
 }
?>

And its respective output:

Vehicle Name (1) : Audi S4
Body Style (2) : 5 Door Wagon
Drivetrain (6) : All-Wheel Drive
EPA Classification (7) : Small Station Wagon
Passenger Capacity (8) : 5
Passenger Volume (9) : 90.8
Base Curb Weight (10) : 4101
EPA Fuel Economy Est - City (26) : 14
EPA Fuel Economy Est - Hwy (27) : 21
Dead Weight Hitch - Max Trailer Wt. (31) : - TBD -
Dead Weight Hitch - Max Tongue Wt. (32) : - TBD -
Wt Distributing Hitch - Max Trailer Wt. (33) : - TBD -
Wt Distributing Hitch - Max Tongue Wt. (34) : - TBD -
Engine Order Code (40) : 
Engine Type (41) : Gas V8
Displacement (42) : 4.2L/254
Fuel System (43) : SEFI
SAE Net Horsepower @ RPM (48) : 340 @ 6800
SAE Net Torque @ RPM (49) : 302 @ 3500
Trans Order Code (51) : 
Trans Type (52) : 6

So in the case of this output I wouldn't want the following categories to be displayed because they either don't have a data value or their data value equals - TBD -.

Dead Weight Hitch - Max Trailer Wt. (31) : - TBD -
Dead Weight Hitch - Max Tongue Wt. (32) : - TBD -
Wt Distributing Hitch - Max Trailer Wt. (33) : - TBD -
Wt Distributing Hitch - Max Tongue Wt. (34) : - TBD -
Engine Order Code (40) : 
Trans Order Code (51) : 

Thanks so much for your help!
