Lifted this from another thread, and I thought I'd be courtious and not hyjack that thread....
So what are are the boost pressures supposed to be anyway?
Let's speak in both psi and bar for convenience...
I think in Autos the boost is limited in 1st and 2nd gears just to protect the gearbox. I've seen as high as 7psi in third and 4th gears, but that is hard to achieve safely on roads (going too fast) without kickdown....
Here's what I have at stock on my '99 lpt:
Idle - -20psi - -1.7bar
1st - 5psi - .34
2nd - 5psi - .34
3rd - 7psi - .48bar
4th - 7psi - .48bar - only momentarily
This is what I'm reading off of my mechanical boost gauge.
doesnt really help as you have a lpt and i have an aero (auto). with my abbott ecu and downpipe i get 1.5 bar (21 psi) in every gear! totally undrivable with traction turned off. so much fun in the dry, cant wait to sort full exhaust and IC

hello all! first up sorry bout spelling, AERO it is ha ha. i know boost level cos ive got a gauge cut into dash. im old school so like a gauge and psi reading. abbott racing are here in uk and have been such a help in recent weeks, i'll trust them with all future upgrades (unless i can do it myself of course) will sort pic's tommorrow unless i can get sum off my phone now
i did try bsr first but they couldnt match software to my car for sum reason. glad its abbott now so i can jus drive over and have a chat and sort any issues i mite have
Essex BOYZ we are lol. i know it well, im from Chigwell (woodford, wanstead. and was just in Hainault with my cruisin mates) ur officially invited to a drive around london with anyone who wants to come on Sunday night! its a cheap nite out with chilled people. i'll post time and place tomorrow
dont get me wrong, bsr didnt send ppc cos it wouldnt down load my ecu settings. its hard to watch gauge on full right foot, but if it dont hit full in 1st its damn close and defo does in all other gears. really is an amazin difference! why did Saab not do this from factory??!!!! :x id like more but really dont fink more power would be usable
will check accuratly tomorrow, but yer thats right. when warm makes approx 22psi vacume (15psi when cold). i am changing my gauge in a coupe of weeks so i will be able to compare
Manual,soft from Nordic -Stage 3 Aero,hardware-Stage 3+++:cheesy:
At idle cold -0.7 Bar
At idle warm -0.8 Bar
On 2nd gear-up to 1.0-1.1 Bar-never tried will it boost higher if I insist.
After 3rd-up to 1.4 for normal drive and overtaking and to 1.6 or 1.7.rarely during stupid driving.
Will see with bigger piping and cooler.
However this needle gauges aren't very precise on my opinion.
checked as promised, and yes makes 21psi (1.5bar) in all gears (all testing done on private road of course). must be nice to tyres now, tcs cant keep up, spins twice in first and again changing into second :evil:
