Good idea...I got one 300 watt amp...and won't be adding anything else but a deck...so I think I'll be okay. But I would like to see if there is a difference.

I took it off and put my original back on (Oil leak stopped) and boy could I tell a difference. Now, it almost seems heavier when accelerating, I plan on purchasing a new one from MRZ soon.
Wow...was the acceleration difference really that noticable? My #1 complaint is the sluggish acceleration on this car...I would love to change that.

sluggish accelaration, is probbaly b/c of the PE delay on the car

I figured that's 80% of the issue...so I'm assuming Vince tuned your car? I wanna do it, but I'm hesitant because I only have a CAI right now...I know updates are pretty cheap, but some people say the difference isn't that noticeable, and others say it's night and day. I just want a solid answer and I'll definitely make that my next mod.

Yea but right now it feels like I'm towing a mobile home until about 3.5k and then I feel the torque until about 5k. It sucks, especially from a stop.

i know my car and i can tell you the truth is in the pudding. the tune on top of a full exhuast and intake improves every aspect of performance when it comes to engine response and speed. i just slapped on the 2.4 intake it's a whole other animal. i'll be getting re-tuned for that soon and bumping the rev limit up to 6.8k with the 2.4 throttle body. the tune isn't going to magically make the car faster if you don't have the proper mods. i've noticed quite a few css 2.2 tuners installing it on basically stock cars and expecting way more then the tune can provide on a choked engine. plus to get the most from the tune you need to run 93 octane anything less and you will notice a difference, i'd beat these guys are running on 87 octane and bitching about it. you need 93 or the car pulls timing back to stock.

That's what I figured...well I'll probably hold off on that then. Do you guys think getting one of these pulleys would be decently effective in my case?
