Hi all,

I just brought a 97 gt libero running a 4g93t.

It has afew evo upgrades such as yellow top injectors and tdo5.

It goes well and sits at 9 - 10 pounds of boost throughout the rev range.

It also has aftermarket bov, walbro fuel pump, fuel regulator.

-------------------------------------------------------

Here are my questions....

1. Will i enhance the performance if i swap the original afm for a evo 3 afm?

2. If i change the afm should i change the ecu to evo 3 and is this safe?

3. What could i expect to safely run as my high boost setting?

4. With these simple bolt on's what sort of power would i be looking at?

( Trying to keep factory ecu whether it be gsr or evo, for reliability )

Appreciate your help.... Cheers
