I did a ported LS2 intake and TB about 2 years ago and only picked up 8/11 rwhp/rwtq same dyno used for the before and after and the car was tuned for both setups so I felt that was a pretty accurate comparison.
I installed a Fast 102 and bolted it on out of the box and picked up 18/21 rwhp/rwtq at peak and had higher numbers under the curve over the ported LS2 unit.

If my C6 gains 30/30 I'll be at 450/450 through an A6 with a AFR 205's and a 224 cam! I just bought the Fast 102 and plan to install it unported. I'll clean up the intake a little but will not attempt to do port work.

Have you installed the FAST 102 and dyno tuned it yet?

Thread revival time, re-tuned the car and had an alignment done. When I was told how poorly aligned my car was and had the tech tell me you should actually be able to feel there is less rolling resistance to the car now. I decided to dyno the car again, and in front of a large audience at a dyno day. Here are the results.

You could change it out your self, if you have some tools and good mechanical knowledge. The hard part is the retune that would be needing after the install. There are some threads on here that will show you how to do the work.

Hay guys, I just picked up my new in the box Fast Intake today and needed to get it installed and dyno tuned. Luckily Geoff Cope at LMR "Late Model Racecraft" was able to help me out. They are located at 11755 West Little York Rd. STE 106, Houston, TX 77041 (713) 466-9900. http://latemodelracecraft.com/
The dyno pic below is a base line pull before the install of the Fast intake and my final pull with the Fast intake manifold installed.
The overall numbers are as follows:
RWHP increase by 28.29 hp.
RWTQ increase by 27.07 tq.
I do have a mild heads and cam setup. Also there is more info in my profile.
I would like to thank LMR and corvette forum member FloydSummerOf68, who helped me decide on this upgrade.

If you have a stock tune it is not so imperative as the stock tune is rich, but you will be leaving power on the table.
Always best to get a tune with a fast or headers for that matter.

If you have your car tuned for the stock intake you really need to retune for the fast, otherwise your car will likely be dangerously lean on wot and will likely need less timing as well, based on my experience.

Good to know info... I guess every time we have a few extra bucks to spend on aftermarket parts we basicly need another tune, So If changing to a CAI, long tubes, intake manifold, high flow cats or cam and the like...retune! I need to find a tuner who offers a pkg deal! lol
Or you could do what I did, buy HP Tuners and a wideband and learn to tune. It's a lot of fun.
