Skip tuning the VE, I never do it on a 3800.
They are a MAF based car, anytime you are deep into the throttle or in any boost it's calculating all fueling based off airflow past the MAF sensor. You also did not change heads or camshaft, so there is no need to mess with it. If you have a big build and wanting to dial in the transients fueling with the VE, then it might help.
I'm not saying jerry's tuning book is outdated or wrong but half the stuff in it is useless for 90% of people modding these cars.
