turbo with stage 1 injectors?

this is my first post so take it easy on me. well its time for injectors and i thinking the casserly stage 1s. Im not keeping this truck forever and do not want to spend a fortune. Hp is not my main goal, under 400. i figured if im going to spend the money on injectors i might has well get something other than stock. i tow an 9-10k gooseneck a couple times a month. in both the 60 and 80 tow tune nearly any hill cause the egts to easily climb to 1250 and would keep going if i didnt let off. not sure if numbers this high are normal or not. the main question im looking for is if it would be worth it to do a turbo, something like a 38r. that way i could have the chip reburnt for both turbo and injectors at once and be done with it. i do not want my egts to get any worse.
Thanks for any input in advance.

Bigger injectors usually result in higher EGTs.

Bigger turbo will keep those EGTs down so yeah the 38r would be a good idea. Then reburn that chip to match your new additions with some new tow settings. I think your on the right track. Plus you already have a clutch so you should be able to handle the new power.

Edit: 1250 is getting high, I wouldn't run them over that or stay at 1250 for long periods.

38R will be your best bet because it is a "drop in" turbo, not custom fab work required.

Sounds like you might need to downshift on the hills...Hate to see you spend that kind of money on a turbo if you don't need to. Keep it above 2200-2300rpm when it's working harder and it should bring the temps down. If it's REALLY working I keep mine 2500-2600rpm or higher and it sings right along. In my case I have to watch trans temps too though. 38R will probably almost be more than you need on just stage 1's, BUT will work fine and I think you would be happy. I am currently running my 38R with stock injectors and a bigger turbine housing and don't have any problems. (I put in the 38R to prep for some 238/80 or 238/100 injectors).

Something else to look into is an adjustable wastegate. On my 80hp tune with my stock turbo I was able to get 1200+ empty but WOT and barely 20psi. In my case I chose to wire the wastegate closed (NOT suggesting this is a great idea or anything) and dropped my temps significantly and increased my boost to 28-30. (Slightly out of the preferred range on the stock turbo)

Now towing about 7k lbs or a little more on the interstate with my 38R my EGT's fluctuate between about 900ish on flat ground and MIGHT climb to 1350 on medium grades keeping it in overdrive. (I am watching the pyro gauge like a hawk going up hill.)

BTW, all this is on 3:73 gears and 37" tires.
