Well there's your problem right there. You are using a fire element LS which Tigrex is most resistant to. I highly recommend you get Tigrex S armor and gem it for the detect because knowning where the other Tigrex is at helps a lot and you won't crap yourself when both are there side by side. The quick eating is tremendously helpful against Tigrex, chugging down those potions like no tomorrow. I'll just sum it out now.

What to have against Tigrex- Weapon: Anything that has Thunder or Dragon element or weapon with high affinity Armor: Tigrex armor (recommended by me) or Cenataur U gemmed for reckless abandon Armor skills: Autotracker (needs to be gemmed), Quick Eating for Tigrex armor. Reckless Abandon +3 (needs to be gemmed) and Razor Sharp for Cenetaur U armor. Items: Potion, Mega Potion, Max Potion, Nutrients, Mega Nutrients, Mega Demondrug, Mega Armorskin, Demon Flute, Armor Flute, Flash bombs, Pitfall trap, Shock trap, Tranq bombs

When Tigrex is getting ready to roar when entering rage, throw a flash bomb. That removes his ability to charge or do any ability that involves him going a far distance except for jumping backwards. Have fun. =)
