Please share a part # for the card style MAF.LQ9 MAF (truck style) is bulky and expensive. Depending on intake plumbing, it can be difficult to find an appropriate location. The LS3/LS7 card card style MAF is only $30-$40, and can be installed in intake plumbing of virtually any size without creating a bottleneck.

I'm trying to decide on cable or wire style throttle body.
Thanks for the info. Based on that calculator I'll need 31lb injectors for 450hp at 80% duty cycle, 28lb injectors at 90% DC. So my head calculation was in the ball park for my L33 swap.The larger injectors are helpful if you add a cheap flex fuel sensor and want to run e85. Your LQ4 is similar to mine with higher compression and a bigger cam. I'm running the flex fuel 50lb injectors and only hit 50% duty cycle with 93 octane fuel, so I have headroom for e85, or about 9psi of boost. With your build, you will be beyond the flow of those truck injectors for sure, the TBSS injectors will be OK, but give you no headroom. I think the 60lb injectors are a good choice. here's a good calculator: https://fuelinjectorclinic.com/flow-calculator
Another thing to consider is which connector is on the injector, body size, and price/availability. I went with the following 50lb injectors because they are a factory reliable injector with accurate data, e85 compatible, stock truck height, EV6 connector (cheap to adapt to my EV1 harness), and very affordable. My current call is inline with yours, 450hp 93/E85, so I could have gone with a smaller injector, but these were the best deal and I have zero issues with them.Thanks for the info.
