Kagem has Trifecta tune and no other mods. however, in some races between GTs (including mine) he has one of the strongest, if not the strongest GT in Greece, with stock turbo.
two days ago, he did some mods to his exhaust (only the final part) just for the sound.
today he went to the dyno -Dynojet.
his numbers are
Power 291whp
torque 49 kN*M !!!!! (don't know conversion to US system)
he promised to scan his dyno sheets and send them to me on Monday.
Will post them soon. From what he said, in 200rpm, from 3000 to 3200rpm, he has a raise of 80whp !!!
