If I decided to get a Procharger for my stock TPI350, what kind of gas mileage should I expect? What about with a modded TPI350? The car is a daily driver.

------------------
91 RS
Black w/ red tweed
t-tops
14x3 Open Element
80 Series Flowmaster
350TPI or Buick Turbo6 swap this summer


88 GTA
Red with grey cloth
K&N Filters
TPIS Airfoil

 

I have alot of mods on my car too. After the prom I got around 30mpg on the highway if I drive NORMALLY. What helped the most was "highway" mode being used in my chip.
