The V8 and Buick V6 throttles will bore through just fine at 70mm with enough wall thickness but yes they are getting thin and very close to the bearings for the throttle shaft have done a few and currently running one on my VS GTS I noticed a small gain in the 2000-4000rpm range but it felt the sam...

Did you notice much change when you went to the bigger maf ? do you have any before and after test or dyno runs of it ?

new to all this and just wanna check the burner above am i right in saying that will burn both the vs v6 and v8 memcals ? and do they do they just plug into the unit ?

ok i had a little play with the excel maf tables when increased by 50% the actual new table gps in the maf table #8 read #num! so im asuming this value is to high for the memcal to handle ?

I have a factory supercharged V6 and am trying to work out how to alter the maf tables to work in with a enlarged maf as you would know if you run a larger than stock maf and don't tune the car to suit it then you will in time burn out your auto the issue im having is i am unable to alter the tables...
