How to tune the A/F curves...

[no_escape]

I didn't see a previous topic about what I'm about too ask... if there is one, let me know.

Here's my problem/question...

The car is running lean in bank one. I can feel it when I smash it and I've had the codes read. I've cleaned and recharged the K&N, cleaned the MAF with electronics cleaner, and cleaned the fuel system. The car came with split second fuel calibrator. When I tune the car on the laptop, do I need to do it on a dyno? I'm pretty sure I'm gonna have too. If so, How hard is it too do for someone whos never tuned on a laptop?

Plus, you think it would be wise to get a A/F gauge since the temp in Iowa changes kinda drasticly from the summer season too the winter season?

Mods:
SC V6 4psi, 190LPH fuel pump, 305RC injectors, jims fuel upgrade, Split Second Fuel calibrator.

Thanks.

you need access to a wideband and/or a dyno that has a wideband

and any good tuning shop can figure out any tuning hardware

x2 on what eye8pussies said! it was a little hard finding a dyno around here that knew anything about split second, but they can figure it out, hopefully their learning doesn't equal to your paying more, but who knows!

ok, thanks guys. I found a shop in Des Moines called Midstate Machine who has a wideban/dyno and knowelage with software tuning.

Now I've gotta drive through the new 4" of snow that came last night... grrrr...
