I just changed to an extender chip and now all of a sudden when i run turbolink and start cruising...EGR % shows 0 all the time...blm is stuck at 160 at idle and integrator at 128 or around there...when i cruise both numbers are around 128

i put in a brand new egr valve and gasket even with the old chip and the % was always in the high 30's during cruise...what happened? i made sure the connection and vacuum lines going to that area were connected...

Unless your state, like NJ, has some sort of special test for low mileage or other special interest vehicles, yes.

In NJ we have 2 special designations. Low mileage (Under 10K miles in 2 years) receives a 2500rpm test (No NOx) and collector car (under 5000 in 2 years) gets no inspection at all, safety OR emissions)

You should chec out your state

another GN in Rockaway! never seen you around! anyway, a chevy buddy of mine told me that removing an egr could cause pinging....not sure of the rhyme or reason to that but whatevs. all I know is that mine was all glogged up and wasn't doin a damn thing.
