TRD/ Magnuson 4.0 Supercharger Tips, Tricks, and Mods

It's a circumstantial mod really.

 

I boost referenced after installing the 2.7 and becoming too lean. 2.8 was fine with no FPR. My 2.5 is a tad rich with FPR. All on OVTune.

 

I'm on ovtune 93 with a 2.8 soon to go 2.6 wanted to be safe-ish.

 

fpr just adds fuel with boost as a reference. more boost more fuel. hows the ovtune @White lightning boosted

 

I would do the FPR when you install the 2.6 and see what the numbers are. With 2.7, the stock fuel pressure on stock TRD injectors was not enough fuel for me on OVTune.

 

Love it. Once I have my 2.6 on I'll do some data logging for a custom tune. Want to take advantage of the methanol abilities!

 

Thanks for the tip. How does one do the fpr mod

 

vacuum line on the fpr attach it to a boost source.

 

you gotta think about it this way too. u have boost in ur intake plenum and the injectors have to spray and the boost is pushing back the injector. the fpr mod just matchs the boost levels with the fuel pressure so the injectors are spraying like in a n/a motor

 

FPR is the second easiest performance mod you can do after the TRD shift knob

 

Looks like I'm not the only one with nasty looking plugs. These all look far worse than those coming off my STI. And it runs the same plugs.

 

You have a 6 speed pro? Did you special order that beast?

 

Which of all the TRD shift knobs?

 

Thanks for the explaining

 

Page one talks about the FPR mod if you need a further explanation on it.

 

No automatics have one too

No I'm auto trans but still got the high performance knob

 

Gotcha! Everyone knows a TRD stamped shifter is good for a few extra ponies

 

At least 5 guaranteed but most have reported 10 extra horses from it.

 

That's why I forked over an extra $5K for a TRD Pro

 

The FPR mod is only increasing fuel at a 1:1 ratio. How can you be so rich at part throttle?
