vtr vs vts?petrol consumption

[evo6]

Has any 1 who owns a vtr ever had a race with a vts?If so, are they miles more quicker?I know they must be a bit more quicker with 16v unit,but is it really worth shelling twice the insurance costs for 1.Dont really wana swap for a vts, as im tryna save for a lancer evo6.

Ive had my vtr from new (2001), and recently Its been using way too much than ususal.Does any1 know what could be wrong?Got a viper filter, and a back box, fitted in the summer, but recently has started to use far too much fuel?

clean exhaust tip, then keep an ey out for excessive black ness, if so lambda sensor goosed, also look out for dip in performance.

The vts is actually a fair bit quicker 2 odd second to 60 and something silly like 8 or 10 seconds quicker to 100
