Stage 1 Vs Stage 1.5 injectors

My injectors in my truck are getting worn out, running rough when its cold etc.

So I figured I'd upgrade to some bigger injectors.

I am stuck, I cannot decide what stage injectors I should choose. They will be full force injectors.

Stage 1 seems great. A little more power, and you can use stock drive train parts.

Stage 1.5 seems good also. A lot more power however I am wondering if my stock turbo can handle it? Also I expect to eventually have to replace the transmission either way in the future. I have the money to replace it if it does go out but of course if I drive normal I hope it will last as long as possible. Will the 1.5's kill the transmission easily?

I am thinking I should go for stage 1 injectors but I hear that people are disappointed in the power not being that big of a jump.

In the end I don't need huge power. (but it is fun) I will occasionally tow a travel trailer or 5th wheel (I am still looking around for them.) I don't plan on getting anything heavier than 10k. I know you can keep the 1.5s tuned down somewhat if needed for towing.

I know this wasn't written very organized but its what I could do.

I'm at this point in my replacement engine build. Been scratching my head as well. 1.5's are very little money more so it is tempting. Hopefully someone with way more knowledge jumps in

I canít talk for people who went to stage 1. I went with stage 1.5 from full force diesel on a stock turbo I had some trouble keeping egtís in check towing in Colorado but the turbo held up I had good tow tunes witch helped. My set up now is hydra with 1023 Diesel tunes with a GTP38R adrenaline HPOP Built 4r100 4inc exhaust stock intercooler. My set up now works real well at keeping Egtís down and lots of power towing.

I also have 160/30’s

I had two major trans failures in the first 2k miles.

I stripped out the forward drum which is common over 350hp. Installed a E4OD long spline drum instead of the 4r100 half spline unit.

Then i Grenaded a triple disk ford reman converter.

Trans temps never went above 180 and it had a modified VB and larger cooler. No warning on either failure.

This was only on a 3.7ms tune 360-370hp.

I also had higher egts than I liked with a billet wheel and ebpv delete 1400-1500 degrees and high boost/drive pressure

So I ended up swapping on a van turbo. But the 38r (with wastegate tightened way down) performs even better.

For just a mild truck I would do a 160/0
A 350hp 7.3 is fun to drive.

Your not gong to find many tuners that will recommend that size anymore.

180/80’s make 25 more hp than 180/30’s at the cost of torque and heavily taxing the HPOP.

Stick with 180/30 or jump to 200/80 hybrids.
