Boost pressure

[tree98]

Wait stop right there!! You most likely have a bad delete, I would bet money on it. I'm not real familiar with the ISL but I'm pretty sure it has a VGT turbo on it. Most so called "tuners" don't know how to make a VGT work after a demandate so a lot of times you end up over boosting. I would think 39 psi on that thing might be enough to do damage. You need to have someone here look at that program. Also once Rawze comes along and sees us talking about an RV he might run you out of here lol,guess we'll see.

Here's what you need https://www.ebay.com/itm/401990863045
That's insite and the inline adapter that you'll need.
