    Mine is installed just downstream of the first O2 sensor. Is it the perfect spot? I’m not sure I’ve just seen that’s where others have put it. Ideally you would have one on both banks. I just have 1 for now and I chose the drivers side since that has cylinder 5 which tends to be the one that pops. I’ve heard others say to mount in the other bank as that one is more likely to suffer from lower fuel pressure since it’s the 2nd rail in series. I figure having one is better than none, but I may add a 2nd later. Maybe @ViktorG will see this and chime in, I know he did a lot of testing of the stock fuel rails. I’d tag him but I’m not familiar with how…yet!?

    Hmmm definitely prefer one per bank, looks like this is a good candidate:

    https://www.amazon.ca/Innovate-Motorsports-3891-Lambda-Oxygen/dp/B013UG0GHC

    may end up putting the wb o2 gauge in glove box, BUT I found a boost gauge solution! this one will read tons of info!

    You guys are a bowl of knowledge here!!! Thanks so much for the input. I may tackle this myself. As pretty much everything thing is bolt on and just replace fuel pump.

    It should be easy as pie.
    I swapped my Maggie w/all associated parts, and fuel tank,off a doner truck,over to my current tundra...then put all the stock parts Off my current tundra back on the doner truck had both running and back together in my driveway over a weekend.

    Lean code update:

    I think i found it!

    can one of you fine gents take a picture of the vacuum connection on the bottom of the front of the blower, just behind the top pulley.

    just on top of the coolant crossover.


    one of you fellas called this out many posts ago!




    Really, really....D3 helped me locate the leak when i went by there yesterday

    and yes....we are doing the stage 2. Damn the torpedoes!

    just did the chik-fil-a test..chicken mini's!.....idling in line. no code & it's 48 here.

    I'll send pictures of the culprit Monday...I used an old pipe band to fix it.

    THAT!

    my hose is a smidge bigger....it was leaking when it got cold.

    you could wiggle the hose & see the air gap.

    i used a pipe band to MAKE it fit.

    Yes. Magnuson dropped HP Tuner in favor of OVs Tuner to make this happen.

    I just ordered up a Magnuson kit for my 21’ Pro. It’s hard to get away from the fact that Magnuson was the OEM provider for Toyota for years. Not to mention their kit makes plenty of power for me. I don’t plan for anything more. When are you expecting your kit?

    as a guesstimate....is the Magnuson turning ~8psi? for a 160hp gain.

    I gained 120hp off of 6psi

    Magnuson claims 162 hp gain. They put out like 6.5-7 psi from what I’m seeing and being told.

    I have not seen a difference in performance.

    What would such a leak affect?

    We are living in the golden era of horsepower.

    From >500hp Tundras to 707hp TRX's...to 1000hp Tesla's....to flat plane v-8 american supercars.

    enjoy it fellas. I am.

    Was it really hot out when you had yours on the dyno? If so I’d be curious if you had another go in some cooler weather if you would both make a little more boost and make even more power. Mine hits 7psi usually. I know Harrops website claims 160hp gain in stage 1 as well. Also, how soon are you planning to do the stage 2 upgrade? I’m excited to see your results. I’m on the cusp of ordering the pulley and injectors and a remote tune pack. I may do it any minute, hour, or day now depending on how impulsive I am.

    yes...it was 93 in the garage + 1 billion % humidity

    Stage 2 - waiting on the parts from Harrop. 1 week? I had to get the grippy pulley, the regular 80mm was backordered.

    What did Harrop get for the parts? I checked with SDHQ and Superchargersonline. Seems like the injectors are gonna run 600 and the pulley is 140 for a Harrop or 165 for the griptec. I’ll probably just get the injectors through DAP with the tune pack. I’d budget for a different intake as well on stage 2, it seems like there’s a good chance we will exceed the MAF voltage scale with the factory 3.5” intake tube. Harrop said some customers find that limit on the 80mm, and I’ve seen a few cases now where they had to upgrade the intake to get it tuned right.

    Our tuning talk was good.

    I'm getting the safest, old man tune to 500whp. Nothing wild. safe AFR's.

    firming up the 1-2 shift a tad.


    and my Trans cooler comes in soon.

    $750-ish for parts. The MAF might need a larger intake coming from airbox - he explained air math, but I zoned out...we will cross that bridge soon.

    DAP says I can expect 40-50hp gain from going with bigger injectors and a tune with the 85mm. Switching to the 80mm he said is good for an extra 20-30hp on top of that. Not sure if it’s worth the extra 450-$500 for a pulley and a larger intake for that much power. Not to mention the added stress although likely minimal from the higher boost
