Weather was close to before, if anything it might have been a little cooler on the after changes run. Touchofevil is probably right, the more you do the results are smaller.
My next Mod is converter,hope to see something there!
Bottom line is if someone changes from shortys to a set of 1500. dollar LT's your just not gettin your moneys worth.

Since you have a Procharger, you will reduce back pressure on the exhaust. This typically reduces the amount of boost you will get. I have seen this happen on many STS and Magnacharged vehicles when going from manifold or shorties to LTs and ORY. What was the boost level before and after the LT swap. But on your application, you will see less improvement, versus someone who has basic bolt-ons (sans boost). Also, that is why Pacesetter are the better bang for the buck, as they will not cost you $1500! Unless you are going all out ...

I'm still seeing 11lbs of boost at max although I have the 8lb pulley. Thats about what it was before and I was convinced that the cats were plugged,.... no cats now.
