Yeah, all you do is loosen the 2 bolts, hold it down all the way, and tighten the 2 bolts. I am suprised you haven't heard of this before.

Talk to Jeffery 10x2 also
he has a supercharge wastegate bypass trick too..( especially for when you change the pulley on it.. and the overboost protection kicks in dumpin out your boost )

Sounds like an easy mod but........
If it ups the boost at part throttle, it must negatively affect fuel mileage.
I'm averaging 15 mpg now...mostly city driving.
Any comments for you GP guys on this?
I just went out and played with the adjustment. Haven't driven it yet.
There is about 3/8" of total movement. It had been set at the factory near the top.
I settled on about 1/2 way and will let you guys know the effect after my trip to Vancouver this weekend.

ok, i look at it this way. if you want both performance and fuel mileage, you must give and take from both, i have yet to hear a performance car say" i just turned a 9 sec 1/4 mile time , and.. i also got 33 miles per gal too. an engine is nothing more than an air pump. the more air you flow through it, the more power you get. in order to have that much air, you must keep the proper air/fuel ratio too. this means more fuel too. sometimes you have to make a decission, more power or better fuel milage. myself, when i go to the track , i pay 4.70/gal for race fuel, and would rather have the power under my foot than being able to get to the track for 2 bux in gas.
this is just my view on the milage wars

But if I ***** foot it on a long family haul with the cruise control set at a 60 mph I expect to get decent mileage.
Sure I only average 15 mpg now because of trips in a small town that last about 10 - 15 minutes.
With not change in driving habits my mileage went down from 18 to 13 mpg when I installed the drilled 180 thermostat...just as an example of why I asked the question whether this subject mod affected fuel mileage on the average.

Well.. I personally find if you want to save gas on long family trip..( or any long trip ) ( especially with hills involved ) is to actually NOT use cruise control ( only when you're foot is tired ). Strange as it may sound.. this has always worked for me on long hauls. It'* to keep a steady foot throttle ( thus burning the same amount of fuel all the time ). You'll loose speed going up hill.. but you'll gain it back if not more coming down hill and give you enough added speed that when you go back up hill.. you don't loose that much speed.. if it then comes to a nice level stretch.. the speed will level itself out. The reason why I'm sayin this is if you gently put your foot on the pedal just to feel the cruise accelarating and decalerating.. it doesn't make much sense as it adds throttle ( pending on the angle of the uphill.. it maybe quite a bit more ) just to maintain speed going up the hill.. but then when it comes back down... it'* right off it to maintain the speed.. then back up the hill.. it burns more fuel to maintain speed. This may not work for some people pendin on their terrain.. but I always seem to burn less fuel then most other people that way ( providing I"m not chasing a bunch of Ricers along the way :evil )

Your dead right.
The only time I ever use my cruise is on straight and level highways.
We only have one like that where I live. I'm headed for it in about an hour.
The rest are twisty hilly slalom runs.
I only get 150 mi to a tank in my Firebird.....the Bonne is a little better.
