ok heres the deal. i did researc ha while back on what pipe to get on my moped. I got the techno estoril because i was told on quite a few occasions(even my mopedguru) that it had the highest rated speed for aftermarket pipes and all of the people that gave me input said it kicked the biturbos ass easily. now after installing it and changing the jet (from 51-56) still all the mopeds with biturbos kick my ass easily(especially in excelleration). I dont really understand why. these mopeds are the same kind(targa lx) with a supposedly worse pipe and they are killin me. whats wrong with my moped?
