Thanks for the comments guys, my car does put some serious power at high speeds due to the big profile camshafts I guess. My friend went nuts after seeing the outcome, he actually had a bet with me thinking he was going to beat me, lol! The mods on my car do sacrifice some low end power but goes crazy up high since the 296 duration shrick camshafts remove power from down low and adds it at high RPM's and the same story with the supersprint headers, this is the list of mods done to my car by kelleners-sport:
Shrick camshafts (296 duration)
Supersprint headers
Secondary high flow race cats (100 cell)
Kelleners-sport rear mufflers which are actually eisenmann race mufflers with a kelleners badge
BMC air filters
A custom ecu tune for all the above mods
I added RPI scoops
A full 15'' brembo BBK set
Ac schnitzer type V wheels with spacers and H&R springs.
