Re: For those who run with the K04 setup-what is your HP(WHP or engine HP)??? (drm916)
It is not low. I haven't seen more than 222whp with a KO4+standard mods like yours. Also, the 222whp was on an Audi TT-180hp from the factory. The TT always makes more power than an AWD motor with the same mods(lower compression+dual downpipe~3" downpipe.) The GIAC KO4 chip that drm has spikes to 22-23psi for a sec., holds 20psi till 5000rpm, tapers off to 15psi, and beyond 6500 holds 12psi till the rev limiter. It also depends on load(uphill/downhill)
Bugpower is right, peak boost does not matter for power. It is the ability of the turbo to keep the pressure in the cylinders for longer. In my opinion, the KO4&your motor will be most happy with 1.25bar=18.3psi till 5500rpm, down to 15psi till redline.
