I had (ok still have) code 52 and the car runs like ass, especially if you try to get above 4k rpm or more that 35% throttle.
shielded cable is not expensive you can find old networking 10 base T cable for free or even use 18 gauge speaker wire.

be a jerk to people who are trying to help you...brilliant

I guess some people are different than others...I know most people would rather be able to monitor their motors to make sure they are healthy before they start to bump up the power and start slapping on mods that they know nothing about

Your Lex and 550 mod is pretty much useless with the stock exhaust btw....You can pump all the air and fuel in that you want, but if you cant get rid of it then you wont make more power...Engines are just airpumps...


Fix the code 52...the right way...then come back and we can help you with your other issues.

First few steps to mod a vehicle are always the most neglected. People think when you just start installing new parts that it'll cover the old problems.

Step one. Make sure your vehicle is healthy enough to think of modifying it. You can start by doing a compression check.
Step two. Do ALL of your basic maintenance needs IE change oil, spark plugs, radiator flush, belts and hoses etc etc.
Step three. Make sure all of your suspension and brakes are functioning properly. What's the point of having a fast car if you can't handle or stop, just because you don't care doesn't mean you need to hurt someone else in the process.
Step four. Do your most basic mods first. Free up the air flow, full exhaust and the apexi filter will give you the biggest gains for cheap. With a full exhaust including a down pipe with the integrated elbow, you won't need a MBC as the less back-pressure will raise the pressure a few PSI.
Step five. After you've helped the engine breathe a little better, lets get some gauges to monitor a few things. AFR, oil pressure and oil temp. Yes I know the stock gauge cluster has an oil pressure gauge but I'm not so crazy about it.

With a few bolt on parts on a healthy engine, you can get to 300 whp off of the stock ct26 without much cash invested.

So I take you have no idea why the 1UZFE (Lex for Toyota Motor Sales) meter and 550 injectors are used.

More air...more fuel...maintain idle AFRs...raises fuel cut.

I think the point he was trying to make is that it's utterly stupid to raise fuel cut for stock exhaust.

no man I’m not trying to be a jerk, what I’m trying to make you see is that not everyone can get all these thing when they need it. Trust me i know i need to open up my exhaust,ic setup,tune,.etc why haven’t i done it? I’m a student and work part time so time and money is not on my side yet so i get what i need when i can.
I appreciate all your help and everyone else’s.

as of code 52 it is gone and the least of my worries now, i went back and covered all the wire with loom just for a little more protection

Hey IndigomkIII
great info and so far i have checked off steps 1-3 on your list. I have put fresh oils (engine,tranny,diff) and coolant 600miles ago. Sparkplugs were put in swell but as well. Since i rebuilt the motor there is brand new everything. New seals, belts, hoses, every single vacuum line is new also.The car is very healthy as for maintenance
I plan to order a bic down pipe this friday and a better IC setup soon after, but like i said before i can’t get it all at once so bare with me

I looked around and it appears pl8-500s are a thing. They are either long discontinued or less likely but still possible a china replica.

yeah man i kid you not theres two zeros after the five haha id post a picture but its to much of a hassle just for a darn pic.
what would have happened if they weren’t impedance? I’ve read some stuff about that before but can’t remember.

If they were High Impedence injectors you would have to remove the injector resistors. But the ones you have are low impedence so you should be good.

would’ve lost your money on your bet haha well the ones i have look exactly like the ones on the attached website and when i had them off they seemed like good quality. i had them cleaned before i put them back by a friend who rebuilds injectors.
