Tuners I have a question...

bboteler · Feb 22, 2013

I have heard several different things from people who are not tuners so I need your input. I have Warren 175cc injectors with stock nozzle. Some people have said there is no benefit to new tunes because these act like stock injectors and there are nothing different in a new tune from my old one.
Others have stated anytime you change injectors you get the most out of them by having tunes written.

Note: I have stock tunes from many tuners here and I'm not pitting anyone against another I just need to know what you guys think.

Also yes I have changed my turbo so I know that factors in overall but I have only changed the compressor wheel and modified the exhaust so it's not completely different...just better flow and cooler egt's.

I'm hoping to center this question around the injectors and talk to individual tuners by pm about what will work best with my set up as I lean toward live tuning in the near future.

More air/fuel in = more output.

A tune written for your turbo & injectors will yield a more optimized output vs custom tunes for stock chargers & sticks.

What turbo are you running?

Not anything with a name brand on here. I had it built by a local shop. Nothing fancy...upgraded internals to the stock turbo with Garrett rebuilt kit, batmowheel with necessary machining and a 20 degree clip on the exhaust wheel. The a complete balance to the whole turbo. I don't know whose or what it's comparable too...I really just wanted to go my own route and see how it worked out. I'm very happy with how it's doing.

Everyone tunes differently..... with my stock injector tunes you won't need a different tune for more cc because i was already calling for more fuel than the stock stroke was delivering.... you only get more power on the low end over a 155 by going to a 175 with a stock nozzle.
