block egr or 3" exhaust . which one should I do first ??

[sherman tank]

Hi everyone.
I have a 2002 gu 3lt auto that is stock standard and has done 94000 km, but needs more giddy up n go,
my question is should I block the EGR valve first or fit a 3in exhaust first or do both at the same time ?
I would be fitting a oil catcher at the same time.
The car does a lot of heavy towing and I"m trying not to kill it. (yet).
Thank you in advance for your information

I would block the EGR and install dowes and needle valve to control your boost peaks and spool up and if you can afford it do the exhaust as well.
Make sure you have an EGT and boost guage to monitor temps and boost.

The first thing I would do if you haven't already is fit boost and EGT guages.
Blocking the EGR won't increase power much, it's more of an engine saver mod. Fitting a big exhaust and a power chip will get you more power, a bigger intercooler will also help.
As Nisspat mentioned you will most likely need to fit a Dawes and needle valve to properly control boost.
