What to do next?

[Harvey Halabookie]

I have an '04 Yukon with a 4.3. My mileage went up a bit after installing the K&N FIPK and Flowmaster Exhaust, and switching to synthetic oil throughout. I didn't notice a change in power though. I've set aside $400 for my next mod and was thinking of one of these:

 

1) Electric fan kit

2) Programmable Tuner (Jet, Superchips, etc)

3) Mass air flow sensor

4) BBK Throttle body

 

Any ideas on which would be the best bang for the buck? I was thinking the tuner because I could use different modes for towing, economy, etc.

 

Thanks!!

Go for the tune!

Check out http:wait4meperformance.com. It's the best $150 you can spend. (my opinion of-course).

gonna say stay away from the MAF's and the TB spacers. I would go with a tune from wait4me performance. I just installed one and it increased gas mileage and power... alotta power. Programmers do well too but a tuned pcm is more custom and takes better to the mods you already have. And its cheaper!

Thanks for the replies. Guess I will go with a tune or tuner next. Any prefernce when it comes to the tuners? (Jet, Hypertech, Diablo, etc?)

 

Surprised on the response about Flowmaster though. I've used their stuff for years on other vehicles and thought it was great.

 

As for the TB, I didn't mean spacer, I think that is junk especially with the Vortec engines. I saw that BBK makes an actual Throttle Body to replace the stock one. It is supposed to flow more air and give better mileage and performance since it is the choke point once you have upgraded the intake system.

 

Thanks again.

The K&N helps air flow, but does not stop anything. You may get increased fuel economy from it, but it shortens engine life.

I would agree completely with the K & N comment. If you had an oil analysis done you will see it come back with unacceptable levels for silicone and silicate (sand and dirt)

 

It will certainly let in more dirt. Is it too much? You will have to decide how much is too much on your truck. For me, any additional dirt in my engine it too much.

Of what you listed, I would go with the Tune then E-fans, then skip the rest.

I was wondering how the wait4me performance thing worked, i have an 05 gmc sierra, and was going to buy a hypertech programmer, but if this is better and cheaper, i will go that route, please help me out.

Definately better and cheaper. I would NOT buy a hypertech with YOUR credit card.
