Thanks again for all the posts guys. I realized that I had to reset my timing belt due to high engine temps, poor performance when cold, and failure to get past 140km/h...all of this after a port n' polish, and broken timing belt. I did this about a week ago and did the afm mod along with changing the crank pulley( I used a torque handle and impact wrench socket...after breaking 3 regular sockets).
THe car now runs to 160km/h very quickly and has a very aggressive launch at near to and full throttle...decent tire spin.
Next on the list of mods is an improved downpipe and cat deletion.
