:tu:good price too!

does delivery valves hurt fuel economy or are they a good way to get good dependable power as well

They are a good way to make alot of smoke and heat.

so does anyone have any ideas what i should ad for the most effective power and economy next. Im taking my truck in to get it dyno tuned and to have my pump timing advanced to 15.5 and the shop say that it not smart to aim for mor than 275hp with the stock turbo because of egt but dont have money for a 1000+ turbo yet but would like a little more hp without causing bad egt and mpgs any help woud be helpful just was kind of thinking 4k springs cause there a sale at ddp for 3k and 4k for $150

4k gsk talk to dieselpap, you can let the middle spring out until you get 60lb valve springs.
60mm compressor upgrade.
14cm exhaust housing
181 dvs
SDX IIs

what do you mean let the middle spring out, and what 60mm upgrade are you talking about is that just the hx40 35 hybrid system that high tech turbo makes

No need for the 60lb springs if you have an auto unless you holdit in gear it's not going to go past 3200 RPM.....as far as DV making power.....yep they can if you get the right ones a set of 191's are okay but .022 or .024's are better. Just stay away from full or lazer cuts unless you like fogging people out and LOTS of heat.
