90 6.2 v8 gmc performace trouble !

Hi, I am experiencing big problems with my land rover 90 6.2 v8 gmc fitted with a Santana box.

I'm shocked by its poor performance!, I only brought it as it was suppose to pull like a train at speed, yet I can tell no difference at all between this and my other land rover 90 tdt 200, with a 3ton trailer on the back it still dies up a hill exactly the same as the 200tdi yet its a 6.2 v8 with 300lbs of torque and 160bhp.

I just can not understand this!, has anyone got any information or know anything I can try, as surely this can not be right?

Would appreciate any help at all guys.
Thanks very much

Maybe they lied and sold you a 200tdi...

FIRST make sure you are getting enough FUEL through the system.

Hummer V8 engines need LOTS of fuel, so fix clean new filters first, then try again.

Almost always, loss of power such as you describe is a symptom of fuel restriction, and that is usually due to dirty filter(s) clogging up.

Don't forget that there's a strainer on the pick-up pipe in the tank, and that can get blocked too.

Blow air down it to clear it temporarily if you suspect it.

Hummer engines should pull strongly.
