no point putting a dp chip in it if its not a 2L-TE.
Turn up the boost and the fuel.
Exhaust will do a little but not much.
Intercooler may also help.
Turning up the boost on a ct20 cost me $3.30 from supercrap for some washers.
Cheers

easiest and quickest way for more power then is to crank up the boost.
Stock boost is 8psi.
Going up to 10-12psi is safe on a stock turbo motor.
Can add washers behind the wastegate or buy a turbo tee.
Dont need to turn up the fuel as its computerised.
Need to have a boost guage though.

what he said, washers for the win. buy thin ones to give you the most 'adjustability'

id recommend getting a pyro as well if your doing it yourself as a ct20 pumping 12 psi will heat your intake air more and risk even higher egts. I cant comment on how well the lte regulates the fuel on higher boost as far as egt's go.

from memory 12 psi will make a 2lte cut out due to 'over boost'. I would not go quite as high as that maybe 11 or 10 for more longevity.

note that it will never fly, but you should see improvment.

id look at intercoolers later and try this first.

here is your new gosple
