GM STAGE 1 w/2.8 INSTALLED!!!!!!!
Hey guys just got everything up and running let me tell you it pulls soooooo hard. I am getting around 16-17 pounds of boost and it is great. Got one question though when I am around 5600 rpm the exhaust pops is that because I need to get colder plugs I just ordered the ngk two steps colder so hopefully that will fix the problem. When my local shop opens back up I will be at the dyno!!!!!!!!!!!!!!

if you are getting a higher psi than you should its not a positive ... it could mean there is somethign restrictive in your exhaust ..like a cloged catilitic converter ..I am just heading out to lunch maybe someone else can go into more detali ...or you can search for cat issues I think someone has a good description

exactly ..lots of people having problems with stock exhaust and stock cat's ...if you are boosting more than what you should for your pulley size you could have a restriction in your exhaust ...regardless of if it is stock or not

I am getting the same amount of boost as BlackSS, i would be curious if the 16-17 is right at readline for glockglade because i only noticed that i hit 16.9 with another person watching the boost as i drove it all the way to 7K. When i was on my own the highest i saw was 15.6. Also glockglade does a have a 3" exhaust that may be dropping his boost some. I will look at my car more closely on saturday when i install my exhaust but with a quick look the other day it seemed fine.
Edit: Toolmaker has the same engine setup and was seeing boost very close to me....

you also have to remember that you have intake and exhaust ..which will effect your boost levels since it flow more on both sides of the SC

The a/f ratios should be safe with a 2.8 inch pulley with the reflash right? I want this same setup for my car as well. Hopefully I can get this before the 29th because I will be dynoing my car on the 29th

glockglade, are you able to rev near 7k on the tach? With so much "wishy washy-ness" there have been people saying yes and people saying not quite on the GM Stage 1 rev limit.

With Stage 1 I have successfully been to 7K a dozen times since yesterday. There must be a few more rpm's left cause I still have not hit my rev limiter and II have been beating my car since 3 yesterday.
