Default 75 or 90 horse injectors?

in my sig u will see the few mods i have to my truck but the next investment id like to make is injectors ive made up my mind not to get 370 marines id rather do it once and be happy then to install them n be sick. i dont like the price of ddp injectors but thats who im leaning on but should i get 75 or 90 with a stock tranny will it hold? its got alot of miles on it. pricing i got was 674.10 for the 90s and 539.10 for the 75s with no core charge. what are yall thinking?

I would focus on the tranny before you need to buy a whole new one. I would look into a good convertor and a good valve body will go aways on trans reliability. Then you can look into to adding more power with injectors and a turbos and such

Im just gonna throw this out there for injectors since the guys above already pointed you in the right direction so you can do some thinking and shopping for when the time comes. SDX seems to have great service and product from what i hear. I havent bought any yet but i do plan on using them very shortly, and their prices are not as high as DDP. Just a friendly suggestion.
