i found a write up to make an egr simulator, its for a 98 gm 4 cylinder, and im wondering if it will work for the 3.8 v6 and other models with the same egr valve. also, does anyone else have any sort of info on a simulator? the egr needs to stay in the vehicle for emissions, and cant just be left unplugged. here is the write up http://www.verboom.net/projects/spee...729/index.html

 

If working properly, the EGR has no effect on power and may actually improve fuel economy slightly by allowing more spark advance. So, why bother with putting in a simulator??

 

i know the egr has no effect on WOT power, but it really dampens mid range power and response in situations using 1/4-3/4 throttle, and also really dirties up the intake tract. i know this for a fact that it frees up power. i repaired the clogged egr valve on my blazer and once it was working correctly, i lost almost all my climbing power and required me to downshift into third just to climb an 8% grade. once i unplugged it, it went back to the normal 4th gear tcc locked climb. and no one likes a carbon filled intake

 

i just got an LS6 intake coming for the ls1 and I have egr, i've read the threads but i think im going to just blank of the exhaust connection and leave it plugged in so it doesnt throw a code??

 

it will still throw a code if its blocked off and removed. my egr on my blazer was plugged with carbon, and even being obdI it had a code for egr low flow. now its just unplugged and has a code for circuit out of range/short to ground.

 

ah i see, i was hoping to leave it plugged in but just with a blanking plate, does it just throw a code and not affect normal driving, i dont want it to go into limp mode etc??
