So after reviewing comments on one of my earlier posts and reading some of the of lastest posts, I think that I'm going to go with 5star tuning: 87 ecom/87 tow/91 perf? Just seeing what the norm is for the tunes. I'm looking to get the performance and improvment of the gas mileage. I tow a jet ski and sometimes a 22' Mako boat but the jet ski is hardly any weight in the fiirst place. Again to refer to my truck, I have a 2005 5.4L Supercrew, 2" autospring leveling kit and 305/55/20 Nitto A/T 20x10 Mazzi Hulks. I have some bolt on engine parts such as K&N cold air, throttle body spacer, Jet MAF sensor and a Flowmaster 40 series dual exhaust. You guys are alot of help and appreciate your timely feedback.

 

To correct the bolt on additions to the truck, I will be putting my stock MAF back on. So a JET MAF is available for sale

 

You will also need custom tunes to correct for the K&N - and get rid of the TB spacer.

 

For reference - this was the thread the OP was referring to: https://www.f150online.com/forums/ch...r-my-5-4l.html

Washoobi tuning was already covered.

Why would I need to get rid of the TB spacer? The TB spacer is not hurting nor improving anything if I'm not mistaken correct?

 

Your answer was in your response...they are a marketing gimmick, a $$$ waster if you will, they do absolutely nothing for your truck...you'll hear some people defend them and say that they are the real deal, those same people will also tell you how they can feel the added HP their drop in K&N filter added. If I were you I would return it (if you even can) and put that $100 buck or so to better use. IMHO.

 

O ok well in that case it can stay on but I will however get rid of the Jet MAF sensor. So bc of the K&N air induction, I need a custom tune from what I have been told. So I guess 5star tuning would be able to handle that. Also what is the difference in price from a normal to a custom tune or again would that be a question for 5star? Has anyone else needed a custom tune and if so, could you tell the difference?

 

All TB spacers do on a computerized fuel injection engine is make noise. The only exception is if you are putting a nitrous kit on it, then you need one.

 

A custom tune is going to require Dyno time which last time I checked is going to run you a few hundred buck. Your setup is a common one for some people and most of them get by with either A) Disco the battery and let the computer relearn, monitor the truck and watch for a CEL or B) Get a tuner yourself and run a preloaded tune...and hey if you got rid of that spacer you would be part way there to a nice Edge Evo which is a good tuner.

 

You don't need a dyno, a mail order custom tune will be fine. It will be better than the default canned tunes that come with the device.

 

^^^ Sorry - for CAI's, it's not that easy...

Additionally - these trucks have been known to run as lean as > 15:1 in Open Loop and NOT trip a CEL. ONLY direct A/F measurement will tell you with certainty.

BTW - I have several mail-order custom tunes, and I do my own datalogging (c/w wideband) - they are dead-on.

 

Huh, learn something new every day, never knew the tolerances were that wide, thats pretty dangerous. I really don't care for the whole CAI thing anyway, and I'll leave it at that before this turns in to one of THOSE threads..

 

Thanks guys for all the information. Need to get that waste of money MAF sensor off and get the tune most likely from 5star. You guys are a big help. Thanks again
