I'd certainly recommend Motion Lab in Charlotte if you're willing to drive that far. Take a look at my review HERE, it should answer most of your questions. I don't know of anyone specifically in Charleston to recommend but one of the guys from that area may. In terms of price I'd say you should expect to pay anywhere from 300-600 depending on what you are looking for and who does the work. Those numbers are based off of quotes I got and what I actually paid. Also keep in mind that you need a Uprev license so that will of course add to your cost and there are several choices in that category as well.

When you say "throttle map", I'm wondering what you mean exactly?

I have had my truck tuned twice by Z1 in ATL, retuned because I added more mods, and was happy with the tune both times.

Phantom recently went up to MotionLab in Charlotte to get his Uprev tune. His review is a couple pages back of his experience which was overall positive.

Basically by throttle map i mean tweaking throttle response and reducing drive by wire delay feel. Does that make sense? Im not too familiar with these things as i am still new to this whole area

This is usually all done with an uprev tune although I did not have a normal tune experience...I called in a favor with Joseph Davis up in Asheville

Throttle response is greatly improved with a tune, even on a stock car.

A light flywheel will significantly improve overall response as well. Apart from the aesthetic and acoustic benefits of exhaust and intake, fw is one of the best benefit/dollar changes you can make imo

would you suggest flywheel over say test pipes or long tube headers for overall perceptible improvements? it looks like the LTH and flywheel install are pretty similar in install times so i wouldnt mind doing either for my next project, i'm just unsure if a new flywheel also requires a new tune

I know alot of people recommend a lightweight flywheel. I personally do not recommend this rout...I went with a lightweight flywheel and didnt notice enough of a change in throttle response to justify the slight decrease in driveability. it amplified the already bad chatter out of these transmission input shafts. I kept the original flywheel and always debated swapping back but i hate working on transmissions so i just lived with it. I loved the test pipes and catback exhaust setup i had. not loud at all and very noticeable gains up top. and the best mod was a stiffer stage 1 clutch and stainless steel clutch line.

I agree completely. I felt the exact same way when I swapped the flywheel out in my WRX. I regretted it immediately upon hearing the chatter for the first time and wanted to take it out every day until I sold the car. On the flip-side, If you only tracked the car I'd go LWFW of course. Admittedly I've not done much research on flywheels for the Z because I've got a long long time left on the stock one, but there may be some that don't chatter as bad as others depending on how much weight is being shaved.

Also FWIW, be really sure you want LTH before you pull the trigger. They are awesome, but LOUD! Seriously loud. Especially if paired with a small or non-resonated exhaust.

hmm i guess it's really hard to find a local person that i could hear the LTH's in person. i have the biggest resonators that fast intentions offer, and also in stainless which is supposedly not as loud as carbon fiber. i understand cold start would be loud. Didn't you have HFC's i believe? I'm not sure how much louder LTH's are than those

Do you know what kind of resonators he had?

[djtodd]

Honestly if you use the needle bearing pilot bushing, there is zero input shaft noise. I use a pretty light (13lb-ish) flywheel and have very little chatter at all. Running a good gear oil helps.

Of course its a bit moot in my car with solid bushings and engine/trans mounts.
Controlling NVH really isn't a big priority of mine lol

[Zensation]

Never used the needle pilot. However I did run red line gear oil and that didn't help. Also the noise wasn't the worst part. The worst part was the car shuttering and almost stalling under 2000 rpm if you didn't have the clutch depressed. Let's not forget the purpose of a flywheel it's designed to keep the pistons moving in cylinders in between combustion cycles. It's ideal on a track where there's no stop and go but on the road in any traffic it suuuuuuuxxxx. I know some people really find it worth it but I just didnt.

But then it can go really fast
