My '04 GTO has been returned to me after having the Absolute Speed Stg II heads, Comp 224-224/581-581 114lsa cam and Stainless Works long tubes. Along with a K&N CAI and the stock catback, this combination made 369whp & 354wtq on a dynojet with a conservative tune. I had expected to be in the 390+hp & 370+tq...and possibly is still in there with more tweaking.

My question is "where to go from here?" From experience, what mods are bringing the best bang for the buck at this point?

Thanks in advance.
