tuner question

[98bluevert]

don't know if anyone can help but if you can please do.

Anyone with a 96-98 GT that has PI cams and PI intake.

When tuning with a handheld should i add more fuel because of the increase in airflow and if so what rpm range and how much. would like to wait to get it dynoed until i am done with my mods this summer.

I bumped my fuel up 8% at WOT and advanced my timing 4 degrees. Oh yeah and I only have the PI intake at this point.

thanks. 8% seems like alot will i need more sice i also have the cams. am i just looking for smoothness when i drive.

Leave the fuel alone until you can get a wideband , they are notoriously rich anyway so it should be fine as long as the stock MAF is in place

i have pi cams and intake, my wideband say im rich over 4k rpms, with no tune, i will find out the true a/f ratio this saterday at the dyno
