Are boost jets safe??

[Bobbymudd]

Hello, I have a 1991 300zx TT that has 92,000 miles on it. I have recently completed all of my preventative maintenance and was now wanting to put a light tune on it. I bought a remapped ECU from harry at Z tuner. It's set up exactly for my car. Now I need a way to increase the boost. I bought 12-13 boost jets from concept Z and am now wondering if these are safe. My tune is very modest. Down pipe back exhaust, single cone intake, stock injectors. Harry said the tune was safe for up to 15 psi. I wanted to make sure my boost jets were under that because I read that boost jets can allow boost spikes. Do you guys think I am safe to run this tune long term?

I'm sorry the tune is also for 93 octane

I know it's been awhile but anybody have any opinions?

I'd just get a boost gauge, if you haven't already, and a boost controller. A manual one works fine as well if youre on a budget.

The jets will work. May have a slight initial spike before they taper down, but nothing major. The tune should be fine with it.
2nd on the boost gauge just to keep an eye on things.
