Tuning question.

[Slopar00]

I have an 04 comp g and I was wondering if I can tune it for a pulley drop (3.6) and still run it with the stock pulley til I buy the 3.6 pulley.

I plan on going with overkill. I don't plan on buying the tyne yet I still have some maintenance work to do. So this is for future info when I decide to tune and drop the pulley. Also planning for a plog and bigger maf

you don't tune it for a pulley drop, you tune the engine to make it run better

Do the 3.4 grab a set of speed daddy headers and get a tune

There is no reason to put a tune on the engine absent accompanying mods it is set up for. You'd just waste gas for the most part.

smaller pulley = more air, on stock tune = lean AFR = Knock = bye bye engine!

you can get a boxed tune by letting Will @ Overkill know what you PLAN to do to your engine, it'll get ya close. But to realize the best performance and advantage of mods would be to In-Car tune the PCM.

3.6 pulley isn't much of a change in anything... Save your $ and make a plan. Piecing parts together haphazardly without a clear thought to what you want out of it will just lead to wasted monies as well. Like you said, you have maintenance items to take care of, do that first. Take care of all and any issues the car may have, modding with issues present will only cause even more problems.

3.6, Plog, larger maf is going to give you what? What are you after? What do you want out of engine, car? Make a plan, read, read, and read some more, then ask questions, modify plan... Save $, assemble parts for modding, then go for it.

You do know they run sub 11.0 AFR stock right??

More so around 10.7-10.8 on a wideband, so adding the extra air maybe bring it up to 11.0 or it won't change at all.

I ran a 3.6 pulley on stock fueling and still ran rich, it didn't knock so I left it be.

Ok. Thanks for the input. I have to figure out a cam position sensor issue then the car should be ready for the tune and pulley.
