I'm not sure what the others will say but I have the same tuner as you and mine does NOT boost fool.... I have the option for wastegate on and wastegate off, but neither changes the level of boost i run at WOT

Boost fooling is not intended to raise boost. Boost fooling is intended to keep your ecm from throwing an overboost code at higher boost levels that you may reach when using power adders like a smarty. Your smarty DOES boost fool to about 44psi. (roughly the limit at which the MAP sensor will read)
If you want more boost you need more fuel to spin the turbo harder... If you have reached the practical limit of your turbo, then you also need a bigger turbo. Boost fooling DOES NOT mean you will make more peak boost... just that you won't throw the overboost code in its simplest explanation.

Yes, you will need a boost fooler for several reasons. The Smarty will allow you to push beyond 44 psi easily on the higher tunes, and, a lot of trucks the WG off does not work and you will not get over 30 psi of boost.
Get a Quad fooler for about $75 and you will have a 40 psi limit which is about wher ethe stock turbo is done and you wil never have any boost codes.

No, that is just a resistor to keep the ECU from thinking the electronic WG control is bad. A boost fooler hooks to the MAP sensor betwen it and the ECU. It clamps the voltage so the ECU never sees the higher numbers.

This has me thinking. I wonder if I would see more boost with my setup if I ran a boost fooler? I think my WG on the HTT is set to 38#, & but if I push it real hard I can get it to 42#.

The fact you can run 35-38 psi where you would only see 30-32 cools the EGT's down so they don't spike so high under a load.

Wouldn't change a thing for you if you have a bost elbow and the WG is not contrlled by the ECU. It will stop codes if you push over 44 psi.
I easily see up to about 42 psi with Smarty on #5, then the boost fooler is opening the WG to keep things in check. DP is out of sight on a 60 lb gauge at that point though.

Thanks again, sorry to high jack your thread, just trying to learn here.

So I guess the question begs why am I not seeing higher boost levels? Is something wrong. I have seen boost pressure as high as 34, but that's under a high load and then only for a few seconds before it starts to come down.

Boost is regulated to the factory setting by the ECU controlling the waste gate. When it hits the preset level the WG opens and boost quits climbing. Smarty has the WG Off option that will just turn off the control, but, it doesn't work on some trucks and it is a bit dangerous because there is NO boost control now.
If you have enabled the WG off in the Smarty options then yours is one of the trucks it doesn't work on. If you have not enabled it, try it and see what happens but watch the boost.

Smarty doesn't boost fool, it just remaps the boost tables so the engine won't defuel and throw codes when it hits about 36 psi (I think thats what the stock setting is), but, thats not what controls your boost.

Gottcha! I enable it and it didn't do anything, so I guess I've got one of "those" trucks! lol Don't know if that's a good thing or not.
Thanks no 6, you're a weath of info!
