Just had a tek3 caried out on my MY99 over here in OZ and am quite impressed with the power that I had gained over the Unichip that it replaced
one possible problem though, a boost spike/peak of 1.42 bar or 20psi which explains the impressive power level (201kws atw on a hubdyno ~30kw up on a Dynodynamics atw)
With the Tek3 on a standard internalled 99 motor what peak boost would be safe side I was thinking 18-18.5 psi tapering to 16 or so at 6500-7000.
Is it safe to run such a high level ~20psi even if its only in the midrange ?
I am thinking the answers to these is NO but I'm surprised that this was not picked up in 3.5hours dyno time...................

Previously I was running 17psi all theway to redline and no issues with the Unichip and a Blitz DSBC

I think I already know the answers to these questions but I just thought I'd run it by my motherland cousins as you seem to have the remaps sorted over there.
p.s boost is measured via the DSBC's internal mapsensor which being a digital display its hard to see instantaneous trends but the peak value is stored. A traditional analogue gauge is on order.

my 99 STi5makes peek 1.3 bar with TEK3

I was under the impression that 1.2 bar (17.4psi) was max on the 99/00 engine, and 1.1 was better for longevity of the internals.

Thats what I'm lead to believe too, might be time for a trip back to the tuner. I'll have a look at the responses tomorrow
(time for sleep over here)

my MY99 holds 1.3 bar with TEK 3, put it on the rollers at powerstation on saturday and i was told its been mapped well with a excellent power curve.

1.3 bar for me as well

Mark_S

1.3 Bar for me too!

Peak of 1.5 and 1.3 held here

parso_rex

Is this on a standard wrx motor or an sti/aftermarket rebuild. 1.5 sounds quite high indeed. I imagine its quick though

thanks in advance

yeah 1.5 is quite high, i bet it eats clutches eh Brun

Danbo

On my turbo timer my peak is 1.47bar.......

Would this be accurate?? I dont have a boost gauge.

According to the Defi's the max boost is 1.5 but quickly backs off to 1.3 in the top two gears. This is all on an MY99 complete with full decat, K&n 57i and an all new uprated clutch and billet flywheel
