Yes, shortening the rod causes more tension from the spring inside the actuator..thus keeping the wastegate flapper in the exhaust closed until more pressure is built up...thus causing an increase in boost.I wish it was a GNX thanks Guys. Also you shorten to increase correct. Thanks again

You may have to pull on the rod to get it back on the wastegate flapper arm after shortening it, that is normal, just don't shorten it too much without some way of knowing if your motor is getting any knock (ie scan tool or knock gauge) otherwise you'll be destroying your motor everytime you boost it up too high.
Pump 93 gas will usually only tolerate around 16-17 psi unless you have a stock chip that has way too much timing for that....remember stock chip has higher timing for the stock 13# of boost. Most aftermarket street chips have around 18-20 degrees, stock has somewhere around 24-25 if I remember correctly.
It wasn't as high as the TTA stock timing...as I just did a chip for a TTA buddy...TTA timing is at 26.5 degrees stock at WOT for 16.5# of boost...there's no way you could run that today. The GN had a few degrees lower but I'm almost certain its around 24 degrees (been a long time since I looked at the stock tables) , because remember stock max boost was 13#. No way can you crank up a stock GN to 16-17# of boost with a stock chip...bearings won't be lasting long if you don't blow a head asket firstReally......was the stock chip timing that high?
It's not factory unless your car is a GNX.
Yes and yes THe E85 mix is probably letting you run that 19# ok...that is if you fuel system is keeping up since it requires more E85 for fuel than the equivalent amount of higher octane gas.Is the E85 saving me at this point at those levels? And by the way before anyone asks, I am an idiot because I don't have a scanmaster or knock gage yet.

Get a scan tool before hitting more than 15# of boost before you ruin your fine ride
If you in fact do have a stock original pump, its probably just barely pumping enough fuel to drive it with 10# of boost. The age alone would make it weak. If its high mileage then the fuel sock that is on the pickup of the pump is probably full of all kinds of trash.Would just the hot wire on the stock pump get me the volume I need?
