So I've been thinking of switching injectors and going a little bit bigger to something like ddp 90hp injectors. I currently have stoxk injectors on my truck now (215hp 5x10) with a 145 degree spray from what I understand. Ddp injectors from what I understand are 5x12 at 155 degree spray angle. Is it worth the littlw bit of d difference to switch to the ddp injectors? Is anyone using them? If so how do you like them?

You'll most likely over-fuel that stock HX35. You'll need to tune the AFC and fuel plate to compensate, as well as watch your EGTs like a hawk; they'll climb quickly. HX35/40 hybrid will air better for those 90s, but a better option would be a 62/65/12 (S300). It's a really good all-around turbo. DAP (vendor) has them: http://www.dieselautopower.com/D_tech_turbo_s300_62_65_12_64_65_12_phat_shaft_p/d-tech%2062mm.htm

Rogan- yea that was what I was thinking. Right now my fuel plate is still untouched and I have the star wheel up about 3 turns. I have a 10 plate and a 3gsk for it but am too afraid to put them in with my stock slipping clutch in there.basically I found the injectors on Craigslist locally. They have about 9000 miles on them and I can pick them up for $375 without giving up my stock injectors. That seems like a good deal considering on DDP's website they ask $800 new. I want to get a clutch hopefully in the next 2 weeks and take it from there. But if I can swing the injectors then they can go on the shelf for later use. A for a charger I'm with you something like a d-tech would be a good way to go. But I'm thinking I'm going to go with the super b single. The bigger exhaust housing will keep egts and drive pressure lower, but I know it'll probably come with some lag. I just the 12cm housing with upgrades it would just get to hot to quick. I feel that a14cm housing is a better route for someone like me shooting for 450whp and still be able to hook up a trailer and not have to adjust nothing besides my foot

Just because they are $800 new doesnt mean they are worth it. I would be worried that they are what they are supposed to be buying used. You can get a better built set of injectors for just a few dollars more and know exactly what you have. I would definalty do a clutch first though. I am very happy with my Contagious Diesel Injectors but DFI is the in place to geinjectors from right now. http://www.dfi-performance.com/injectors-2/

Just make sure they have the exact clearance you need to fit
