Ok, so today I made a run to body shop 30 miles from home for some GP HIPO 5-spoke rims. On the way home I noticed they car friggin launched when I went to pass a car going 5 under the 60 mph speed limit.
Then I looked at the boost guage and saw the needle well into the orange and as the rpms rose it crept up past 10. I know the stock guage is not the most accurate way of monitoring boost, but considering the most I typically see is around 7 and that'* with temps in the lower 50'*. With temps in the 70'* and 80'* it'* closer to 5 or 6.
So I am wondering WTF is going on? I got on it again after I got back down to the speed limit, but not enough to provoke a downshift at 63 mph, and still it went up to 8.
I then let off the go pedal completely to see what vacuum level it was and it showed 14.5 (almost 15) idling along.
So is my guage faulty? I don't think so going by how much harder the car was pulling compared to normal.
No, I haven't gotten another CASE learn done yet (hoping to have that done tomorrow).
I later got a CE light and stopped in at ORielly'* and hooked their AutoXray up and found only a code for the EGR (second EGR I've put on this motor 400 miles). EGR pipe shows no signs of cracking. I am going to put a new EGR valve gasket in as I reused the original when I put this EGR valve on.
Would a faulty EGR system cause boost levels to jump like this?
Again, this is how the car is setup up right now:
STOCK ENGINE with stock SC and stock 3.8" pulley.
Autozone Rice Pipe with K&N RE-0810 9" cone filter
3" mandrel bent DP
3" HF resonator
3" piping almost all the way to the new IMCO stock replacement muffler (2.5" inlet, dual 2.5" outlets).
ZZP UD WP pulley
0 Guage battery to alternator cable along with stock cable.
