I just installed the Gibson Supertruck. I love the sound and look, hate the loss of low end torque. I mash out the gas and go nowhere fast. At higher RPMs, it's great but at a dead stop it's like I'm standing still. Anyone else with me or have I overlooked something? With the chip and airbox mod, i thought I had it all (save the omnipresent supercharger I'm gonna try to reset my computer to see if that helps any. Your comments and suggestions are greatly appreciated.

 

i have the supertruck as well. i modified mine because there was too much in cab resonance for my taste. i ran duals out the back from the supertruck muffler. in the process i gained some low end tourque back. i did not feel i lost that much to begin with though. i do not tow so it was not that big of a deal to me. but i am happy with the final product. check out the pic:

 

I'm revamping my first post. After driving it today, it felt like I gained everything back and then some. I didn't have to reset the ECU (although I might just see what happens) so perhaps I or the computer needed to get used to the new exhaust.

Anyway, I am very happy with it now. I don't want to turn the radio on because I love the way it sounds and there are noticable HP/torque gains.

Nice setup by the way LCB150. If I ever get bored with this, duals out the rear is exactly what I'm doing!

 

I've been real happy with both power and sound from mine. The only problem has been that after 2.5 years the pipe broke clean off from the forward side of the muffler (the weld seperated from the muffler casing). Had it mig welded back on and so far so good.

 

I am happy with mine too.

 

I love mine too. I feel like I gained a lot of low end with mine. I beat almost anything off the line except a Mustang GT or something else I don't even try to take.
