Hi,

I just brought a 2003 STI type UK with the following Mods -
EcuTek
APS top mount
P E ceramic headers
P E full exhaust with hi flow Cat
After market panet filter
Uprated fuel pump.

The car runs pretty well but compared to my old STI RA is pretty laggy with full boost(1.5 bar) not being achived until nearly 4K revs in the lower gears.

I took it to Surrey Rolling Road and it made 335bhp and 300lb/ft but the boost dropped from 1.4 bar at 4k to 1 bar at 7k!

Is this normal as it has a pretty small turbo or would a boost controller hold on to the boost better?
Also do the power figures look Ok or do you think I should get it remapped?

Cheers
Dom
