I recently sold my diesel truck. AFter using the truck to pull my bass boat (roughly 3500 pounds), it made me realize just how weak the Tahoe is. I know it will never pull like the truck did but I need suggestions on getting more power without completely killing its fuel mileage. I know I can get a tuner, exhaust and intake but is there any more suggestions? Thanks in advance...

Well fortunatley there are several things you can do.

1.) Cold Air Intake. I would definetly go AEM for our tahoes, or the K&N FIPK. The AEm is going to be a little louder than the K&N FIPK, and the K&N 77 series. I am about to put a AEM on my 2004 tahoe Z71.

2.) Custom Tune. I would go with a pcmforless, or Nelsons hot tune, or Efivelive. You can go to a local dyno and have them do a dyno tune, or have a someone ride in your truck and do a street tune.

3.) Exhaust. This is a hard one. On my truck, I took the muffler off, and ran straigh pipes, so mine is really loud, but I lost some low end grunt, due to the muffler being gone. I believe with a custom tune, CAI, and nice exhasut, you can gain a respectable 35hp. Magnaflow makes anice exhasut system, and it isnt loud. I don't know if you want real loud, or just some more horsepower, so Magnaflow, or Flowmaster. Corsa and Borla are also very nice, but they are $$$.

4.) Underdrive pulleys.

5.)Throttle Body Spacers dont do anything for our trucks.
