'97 850 Turbo Tuning

[pappa]

Want to thank all you guys that walked me through this; I have the problem whipped! I finally adjusted the wastegate out 4 full turns and its like driving a different car. It is very docile without being wimpy. Feels really comfortable and natural to use the throttle normally now. Haven't taken a mileage check yet, but will do so on my next fill-up and get back to the forum with the results. I really expect it to be good.

Thanks again to all; I could not have done this without you. You have all been great.

the cam gears are adjustable and if you advance both of them both about 2 degrees it helps out low end power so you make more power with less throttle. Also as i did a non turbo transmission computer has a lower converter lock up at 45 mph insted of 51ish. huge increase in mpg in the city. look at my sig with all my mods like bigger cams bigger turbo bigger fuel pump and i still get 22- 23.5 city highway combined. 360 to 400 miles a tank if i stay out of boost.
