I definitely do plan on modding though! I love the gains I'm seeing with simple bolt ons.. 300whp NA with 3-4 bolt ons is nice. Something less than 1% of DE's will see unless they are stroked or ITB's. I doubt the Z33 low end torque would really matter when going 60+
that's where the real racing occurs
So I'm sure the mods on the 370 would cancel out what I had on the G and some. I also do have F.I. in my sights (after warranty is up.. I drive lots of miles so should be quick) which is why I'm not that worried about the 5.0. IMO if I want a fast car thats ugly I'd buy a GTO.
The drawback I'm seeing with modding the 370 is tuning the VVEL, I'm sure if someone finds a break through big gains will be see.
