Engine/Transmission (1998.5 - 2002) Turbo boost?

When I put my EDGE on 4 or 5 and get on it the monitor starts chirppin' and shows 32-35 boost pressure. what is the max safe boost and how could I go about fixing this.

30-32 is fine with your turbo, 35 is starting to push the limit. Do you have an adjustable boost elbow on your turbo's wastegate?

Thank you for your reply. No I am pretty sure I can not adjust the elbow. So it sounds as if I don't get over 35lbs. I should be ok. Thanks again

When I only use my SMARTY and injectors my boost rarely goes over 33. As soon as I flick the banks on it can easily go over 40 when around 2000rpm



These HX35 turbo's seem to be extremely tough considering they only pushed 19lbs of boost stock.

I am not sure about your year model of Attitude, but on mine I am able to set the boost PSI that will set off the alarm. I raised mine so that I rarely hear it. I know, that might not be the best idea/defeat the purpose, but I think it's ok where I'm at. I think the Attitude will also back down the boost once you hit you hit your pre-set boost alarm.

You'r exactly right JD, I'll raise mine up and not worry about it. I wasn't sure that the Attitude would back down the boost. What is the limit for a basiclly stock truck like mine? Around 35 lbs. like previously posted by John? Thanks to all who replied.

That chirping surely must be the Juice alarm. Not very load but enough to get your attention. Check what you have your alarms set to, especially for your boost.



I used to run up to, on occasion, 38# of boost when mostly stock with the Juice. Normally 33-35 and never had a turbo issue for over 150,000 miles.
