7gmte throttle body swap

In your solicitation for suggestions you list injectors??? You didn't install the Laxus AFM without installing larger injectors did you!?!

25% more air REQUIRES 25% more fuel.

i have not gotten new injectors yet. goona try and get some within the next couple days. what size injectors should i get? and what about the throttle body? from anything i find online it wont fit the 7gtme engine?
i would like to go big on the injector so the i dont need bigger ones next summer.

You want 550's with the Lex AFM... any smaller or bigger and you need a fuel controller and to get the fuel properly tuned.

The 7ms stock throttle body flows enough air the way it is I don't understand why you want to put a q45 t.b. on. Do some research before you start asking questions like this. If you would've researched you would have realized you can't just do the LEX AFM without installing larger injectors as well. I wouldn't be surprised if you're running lean right now because you're gettin more air than normal and not getting the extra fuel to compensate for it. Run like that to long you'll screw up your engine.

just ordered injector thanx. thanks for the response. from what i was reading online i saw a few people w/ 1j's w/ q45 throttle bodys because they are larger. just a brain storm but i thought larger was better. i guess the q45 throttle and the 7g throttle are the same size. my only question was would it fit, and u still didnt answer that question. i would love it if anyone else can answer this question or is the last respondent absolute right?

The Q45 TB came in a couple different sizes (three, IIRC). It's a popular TB to use on CUSTOM intake plenums and no, it's not a direct fit for the stock intake plenum.
