should I be worried?
So I have a ticking sound that has me puzzled.
I thought it could be coming from the drivers side of the engine.
This weekend, actually on Monday I decided to do the hot re-torque on the diver side. I warm up the engine for about 15min and have at it. I had put this off for weeks because it has bee way too hot. Dam it was still too hot, I was sweating buckets. I had to stop several times to clear the sweat off my head my eyes my shades.I torqued everything to spec and nothing moved. I went to 125 inch lbs and I got movement on the rear two injectors. I gave them about 1/2 a turn and stopped. I put everything back together, I used hair spray form the 99 ct store. It seemed OK.
Fast forward to Tue. I needed to be sure so I went for the boost leak test. Here is my concern. I was going to test to about 30 PSIG, but I ended up at about 40 psig and I forgot to disconnect the MAP sensor! How likely is it that I damaged the sensor, and how can I tell? She is pretty stock and does not have a boost fooler to protect the sensor.
What do you think? Nothing popped and I did not leave the the HP on very long.

Rich had to replace his, he then put the boost fooler back on to protect it. GH use to have different map sensors but haven't heard this for years. I think they mainly used them for better tuning.

If you use a different MAP sensor, you can recalibrate the tune to actually read boost in excess of the stock max of 32-33 PSI at sea level. If you live in Denver, you can read up to 35-36 PSI boost on the OBDII port with the stock MAP sensor.
Cody and I once talked pretty deeply about a "revised" MAP sensor that could take a bigger beating without the aid of a boost fooler. About all it really does for you is it allows the OBDII port to see the actual boost - nothing to be gained in tuning, and pulling the chip leaves you with a funky MAP sensor that doesn't work with stock tuning.
I added a bigger analog boost gauge in addition to the OBDII boost gauge, plus I have the boost fooler for the MAP sensor. I watch the OBDII for daily driving - where the analog is strictly to see if the boost system is up to 100% while passing pokies.
