Dry Kit Tuning?

Normally you don't really need a tune except maybe pulling a little timing. Depending on your mods you may need new injectors (not a bad idea anyway) and a better fuel pump. New injectors WILL require a tune.

I don't have anything major done to the car. Just a airlid and pulley. I understand I need to take the MAF screen out but I read that can cause some issues for automatic cars. You read so much stuff on here sometimes you don't know whats true and whats not.
I do plan on getting some tuning done later but thats after injectors and a new pump. I'm gonna be low on cash after buying the kit and I was just trying to get some fun out of it before the next wave of upgrades : )

I ran a 100 dry shot for nearly a year without a tune on a full bolt-on car.
As for descreening your MAF, when I was looking into nitrous most told me to not remove the screen, something about the way the nitrous flows over the wires in the MAF would be less accurate.
I'm not saying you cant do it, my bother-in-law sprays a dry shot with no MAF screen with no problems so far. Just passing on some info I was told

If you don't remove the MAF screens the N2O will ice up on it and cause you a big power loss.
You definately don't have to pull any timing with a dry system.
Tuning can be done in the PCM, or simply by adjusting the distance between the nozzle and the MAF wires. Closer is richer & less timing.
Most dry systems work fine with no adjustments at all, but there is always room for some improvements to match your combo.

remove the screen just don't port it out cause that causes problems with the way the car shifts. as for no tuneing i've heard after 100 you need to pull 2 degrees per every other 50 hp (150hp=2 degrees)

Any common problems if you do not remove the screen? SLP charged my butt off for their MAF
and I'd hate to remove any of that 'precious metal' that I had to pay for if I do not have to. Do I need to de-screen the stock MAF and throw it back on there?

Well I have a lid and full exhaust...see sig. I run the NOS 5177 kit jetted for a 125 shot. I have the MAF screen still in, and I am on the stock tune. She made 438/504 like this and the A/F ratio was safe according to the wideband readings.

I did however on my previous car before hearing all of the talk about leaving it alone, descreen the MAF on my A4 car. I honestly never saw any adverse effects from doing so. Maybe I will CAREFULLY remove it, cause if done so with care it can be reinstalled sucessfully.
