Disable DRL:

A few sites that give good instructions to disable the DRLs and Auto Headlights. has a wealth of information for Camaro and Firebird owners. Disable information is available at leres' page, bpador's page, F-Body FAQ (about 3/4 down the page)

Camaro and Firebird. DRL control module, a cigarette pack sized black box behind the radio. Pop off front panel over radio and heater ducts, 4 clips. The DRL module is clipped to the HVAC duct. The connectors you'll be working with are not hot but some of those leads behind the dash ARE hot, its best to disconnect the battery negative terminal to be sure. The blue connector on the DRL module has eight cavities, but only seven of them are used. Cavity B is empty. I discovered that if that terminal is grounded, your DRLs are disabled. The black wire in cavity A is a ground, so I took the DRL module apart (easy to do, the cover just slips off) and solder-jumpered the A and B terminals on the PCB. This leaves you with no DRLs, your power hatch and handbrake light still works, and it all looks factory. Easy to undo if you want. A switch can be connected in this A to B lead for DRLs as an option. You are jumping a ground, not a hot wire.

Remove the MAF Screen:

If you are driving a stock intake car this mod will not do much for you. But, a ported MAF allows for greater air flow.

Trans and Gears:

If you have a 6 speed transmission you have a 3.42 rear end, With the 4.10s, your gas mileage is only changed by 1 MPG on the highway and around town it's the same. Auto's Due to the gearing in the transmission, a 3.73 rear ratio is about as short a gear as most will want.
1st gear = 3.06
2nd gear = 1.62
3rd gear = 1.0
4th gear = 0.7
1st gear = 2.66
2nd gear = 1.78
3rd gear = 1.30
4th gear = 1.00
5th gear = 0.74
6th gear = 0.50
