    You're losing power with that AFR.

    Hey any of you experts know what kind of gain I might be able to see when the ucon is finaly released for the 2012.? I have had a hard time finding a definitive answer. I have URD headers, trd supercharger, afe intake, URD exhaust and 2.85" pulley. Just looking for what i can get with the ucon on its own, or possibly info if i switch to 2.7 pulley and larger injectors. Whatever you guys got let me know.

    Thought this would have gotten a little action by now.

    I swear I read something somewhere that's there's 35hp just in tuning with the ucon. I could be mistaken but I don't think I am. That's stock w/ no tuning compared to ucon.

    I may have seen this a couple years ago and couldnt find it again. Im just trying to justify the Ucon, 2.7 pully, some injectors and such when they are finally released from URD for 2012+

    XR-U was down for some time during the transition to new forum platform. The addicts must have picked up a new fix lol

    The exhaust cam gears are good for 27 hp on a n/a engine and the ucon will raise the red line rpm releasing some ponys, then the better engine management will get you more. It is a triple win. And you get the gardian. Best way to get your answers is to call G

    As much as i would like to call him, i have talked to him before on the phone about one of his products. Hes a busy guy i dont wanna bother him. Once the parts are actually available maybe ill give him a ring again. I like the sounds of all that, minus the redline, i would like to keep that stock.

    You can set the redline to whatever you want.

    I am very curious as to what John at IPT had to say about the revised torque converter, and what you ended up doing. I’m URD supercharged FJ Cruiser and just bought a remanufactured toyota trans and about to send in my valvebody to IPT to get reworked. Also wondering should I pay to have the torque converter done also

    All the mods I did on my 96 4Runner with TRD Supercharger serial number 32, the one I always regretted was the torque converter mod.

    I did two. The first one was way to wild. The second one was much better, but unless I was making hole shots, it sucked. Felt like the gas pedal was hooked to a sponge and the truck just seemed gutless unless I was really on it. MPG went in the toilet too.

    So, unless your truck is going to be a dedicated drag racer, I would skip the torque converter mod.

    What I am worried about in peticular is the negative effects tire size and gear ratio have on the stock torque converter. I currently have a 3:73 rear ring gear running my 35’s until I can upgrade my rear differential to a larger one (after I have broke 2 -8” aftermarket ring gears geared at 4:56) At 4:56 I’m slightly overgeared also, but is what my front is geared to also. After researching a lot recently, I’ve found out the symptoms of gear ratio and tire size effects( look at 10:08 and on in this video ) which I’ve noticed on my truck. Particularly the lunging effect while holding the brakes. Also the limited range of power due to possible overheated atf. Lots to think about before I install my new rebuilt transmission.
