At what point do you NEED a tune for a 1993 LT1 Trans Am? My car is below in my Signature.

Basically, I have Dynatech Long Tubes with 2.5" collectors to a Single 3" Split Core muffler dumped in front of rear axle. The tranny has gone from an M6 to Turbo 400 with Trans Brake and RMVB with a Continental Convertor Stall of 4000 RPM.

I also have a fiberglass cowl induction hood that I'd like to mount a fuel rail pressure gauge so I can see it from the car. Does anyone have a good recommendation for a gauge? What fittings are required to mount the gauge fittings on to the fuel rail? Any photos of a similar set up?

I have a PCMforless tune on my '93 with the mods listed in my sig. I'd say it helped a bit especially to get rid of my SES light from deleting EGR and AIR.
