Stage 1's with stock oil pump...

[taylorking]

So if i get the stage 1 injectors for my PSD, how much hp could i get with like a DP tuner? (completely stock truck)

Some guy told me about 110hp was all i'd get out of the stage 1's. true?

He said i would only get about 40 of that with the stock injectors. true?

The truck wouldnt run better off the bat would it, because the stock computer is still telling them to flow the same right? Idle quality may be different shoudlnt it?

Thanks for your help

with out an intercooler i think max you'll get is probably 275-300 rwhp. w/o a chip you wouldnt know the difference between stock injectors and stage 1's since the stage 1's use stock nozzles. Add a chip and thats when you'll notice a big difference.

^^ i think an intercooler would be a great mod before injectors and/or dp tuner

My stage 1's and Wildman chip made 383 HP on a mustang Dyno a couple months back.

You need to replace the stock downpipe if you haven't already, and gauges are a must.

My truck dynoed 280 ish on a Mustang Dyno a few months ago with Stage-1's and Wildman chip.
How can yours be 100hp more?

I think I would get the gauges, intake, TW chip, and downpipe with straight piped exhaust first to see how I liked it before spending big $$$ on injectors. You would be amazed at the power of just these mods over stock. Should cost you around $800 to do all that first. You can still come back later and add an inner cooler, big exhaust, big turbo, injectors, etc if you want to spend the $$.

I'll agree with the gauges, intake, chip, and exhaust first, but these combined won't do a whole lot for performance by themselves. Maybe 40 hp...
And you don't have to spend "big $$$ on injectors." Stage-1's are by far the most power for your dollar, starting at $475 (or less if you DIY).

i dont know how to do the DIY injectors...coud a local machine shop do it?

[taylorking]

and why did that other guys rig get 100hp more than he other guys truck, both with the same mods?

You can buy the DIY Instruction CD to see if it's something you're interested in. You're only out $75, unless you end up buying a DIY Kit, or have me build injectors for you, then I take that $75 off whatever you go with.
Any competant machine shop willing to take time to speak with you is able to do the necessary machining.

No idea on the hp differences.
Except that in general, dynos suck for comparing.
A dyno is really only usefull to gauge your own changes on your same truck, running on the same dyno. Otherwise you're not really comparing similar situations.
