Im thinking about getting a boost fooler for the ram and id like to know if it will work for me. Id like to get quicker spooling from a dead stop. like from stop sign and red lights. I know the best way for this is to get smaller tires but not happening lol.

Thanks for any input

no, boost fooler tricks the ecm into thinking it is a lower boost number when you are running bigger turbo/'s

 

so it only raises the boost at WOT

 

does not raise the boost at all. it tricks the ECM so it won't set an overboost code. does nothing for spool up

 

icic. so when people install it and there boost gauge shows higher than stock its not really? sry a little confused now. i understand what ur saying but i always thought it does raise boost

 

I don't know what everyone is talking about. My mechanical gauge shows higher boost at full throttle (40psi) and it spools much faster below that. Boosted launches are more difficult without it. It fools the ecm into thinking boost is lower than it really is, so it runs it up. Buy it!

 

your mechanical boost gauge is going to read actual. fooler is electronic and only messes with the ecm to prevent overboost codes

 

until he gets rid of the predator, he will never see 40psi and if he does, his tranny is going to be screaming at him. yours is built and you are running higher SW's from the smarty than he can (if he had a smarty) with a stock trans (unless his trans is built and just don't say it in his sig)

 

so then why are others seeing 40 when you say it does nothing to raise boost and only prevents overboost code.

 

i had one on my last 5.9 and it did nothing. they are designed to prevent over boost codes when running larger turbo's. smarty has boost fooling built in anyways.

and to get 40psi there are many factors, load, elevation, fueling etc.... come up to 5100 feet where we are and would lay money that 40psi would be very rare with a stock turbo

 

By the time you subtract the lower ~3 psi from elevation and the compounded effect that has on air density... very rare indeed if not possible without grenading a seriously overspun turbo.

 

ok now that i know. scrap this idea. thanks guys

 

Someone correct me if I'm wrong. I believe cbrahs is correct in that the boost fooler tricks the ECM into thinking the boost is lower than it actually is. This does mean that the ECM will not throw an overboost code. However, I believe the primary purpose of this "fooling" or "tricking" is to prevent the ECM from telling the wastegate to open, thereby allowing more boost.

 

thats what i thought.

 

Also note that this statement only applies to 04.5+ trucks with the electronic wastegate. On earlier trucks that don't have an electronic wastegate, the primary (and maybe ONLY) purpose of the boost fooler would be to prevent overboost codes.
