This car was not built for high WHP but for easy daily driving. The low end torque is good so shifting is not really an issue. It will pull from 1000 rpm on any gear, makes for easy driving. Let's see what I do when the Stillen warranty expires, maybe stage 3 or 4 upgrade.
SC350ZR... Are you having any belt squealing or early belt wear? I eventually had to upgrade to the 6 rib belt system and installed the upgraded idler pulley. The latest EMS is actually tuned for the stage 3 pulley so that the car runs much better when the car is upgraded to the stage 3 pulley. Finally, if you note that the car occasionally seems to run short of gas on hard long pulls, consider upgrading to a high output fuel pump to keep the car from going lean. The fuel pump is right behind the firewall on the passenger side so the high output fuel pump is noticeably louder when you step on the gas, but IMHO it just adds to all the performance mechanical sounds.

I have the 6-rib pulleys and I don't have any belt squeal unless the tensioners are adjusted wrong. I have not experienced the fuel issue, but I rarely pull for long period of time, like on the strip or track. I will keep this in mind in case I decide to upgrade in the future.
