I would honestly say that 106 GTI's arent overly quick. Even another mates tweaked one sitting at about 140-150bhp didnt feel as quick as i thought it would.
Yeh i agree it can come down to driver error, but once your up and running you can hardly take driver error into account....like i said, i was always getting a better start, which was most likely his driving error, but once we were up to a decent speed it was pretty even, me not gaining on him, him not gaining on me! If we both got identical starts i would have thought his would be nipping in front of me.
And nope my car isnt stripped or remapped, just a straight through system with BMC. My engine took really kindly to mods...some react differently! but i got really healthy and noticeable gains......i did keep up with a G40 for instance
Oh and the VTS is quicker than the 106 GTI. Lighter if i recall!
