I will be keeping the 2.4" inlet so a TGV delete isn't neccessary and the perrin is 'bendable' so you don't have to remove the intake mani to install it. I'm not so much concerned about the install as I am the performance benefit, was hoping somebody had tuned with it and had an opinion on it's worth.

I'm also hearing a few rumblings of the high altitude/91 oct combo up here makes the 20g not so spectacular since it can't boost high enough to be it's efficiency range. If it's is only going to net me 25-30whp for a 500rpm spool loss, I may just stay with the 39.
