Non wastegated turbo concerns

Quite a few years back, I replaced my whole turbo with a beans diesel 1.0 A/R non wastegated turbo to fix my turbo surge problem I had after putting on a cold air intake. At the time I had no idea what the wastegate was even for but my main concern was only fixing the turbo surge. Now I am thinking about putting a custom chip on and have some questions about overboosting. I would only want an econo tune and a couple tow tunes, but I don't want to overboost and damage the engine.

I guess my questions are:
What are the chances of overboosting and damaging the engine with a chip, and what about even on the stock setting. I do a fair bit of towing....mainly bobcats and mini-x's but never worried about it before since my truck is not chipped. I don't have gauges either.

Well with stock injectors your not gona see boost high enough to damage the engine and unless you have a boost fooler your engine will defuel at 24ish psi.

if you want a chip you definately need gauges.
egt gauge, tranny temp gauge if you have an auto, and boost.
you wont hurt the engine like the op said. stock injectors dont give enough fuel

Thanks. I feel a little better now. I definitely don't want to be buying any more turbos.

You might hit 28 or 30 lbs of boost. It takes about 45 before anything stock is in danger.
