What are some modifications i can make to better my mpgs? I have a 93 K1500 Suburban, 4x4. It is stock besides the dual exhaust.

 

Welcome to the forum.

Take off a lot of weight. Do a complete tune-up. Run max pressure in tires. Drive like granny.

 

drive most down hill

 

I was thinking cold air intake, Aftermarket throttle body spacer. I have also been thinking of the tune port injection from a camaro.

 

Forget the CAI and spacer. The TPI might help. But you'll need all of the needed sensors, harness, and ECM. Probably need the distributor too.

 

what are you getting right now? There is not much you can do other than drive very "smooth" and don't take short trips. Same stuff you can do to get better mileage in any vehicle. then the obvious tune up points

 

i've heard about HHO kits boosting mpg....thought about adding it myself to my 99 burb. Lots of youtube on it too, and it seems to be legit.

any thoughts?

 

Welcome to the forum. Let's us know how they work for you.

 

clean air filter, new plugs, good fuel, clean fuel filter, no matter the MPG it's 1,000 x cheaper than a newer one!

 

Agree 100%
