My 383 gets a FAST 90/90, set of YT Ultralite RRs & SD Tune It was time to kick it up a notch on my LS6-based forged 383 and get a FAST 90 with LS2 90mm TB, a set of new Yella Terra 1.7 Ultralite Roller Rockers and a SD tune. Ed Hutchings (edcmat-l1) at Automotive Technology, Inc. in Chesapeake, VA did the installation and SD tuning.

I asked Ed for a conservative tune with a richer A/F ratio in the mid-section of the powerband since I track my C5 often at road course events (HPDE). The following is a list of engine and powertrain mods for reference:

Killer power under the curve. Love the big-block torque at 3000 rpm. Just what you'll need coming out of those slow corners on the road course. Nice job by Ed Hutchings!

Thanks everyone. My C5 does feel like a "new" vette since Ed performed his magic! I'm looking forward to running it at the Virginia International Raceway (VIR) road racing course at the end of this month for four days to put it through its paces. It's definitely going to surprise a few new Z06 and Porsche GT3 drivers there. Thanks Ed!

Ed is planning to come out to Virginia International Raceway (VIR) on either 31 August or 1 September during an HPDE to data log a few sessions with me at speed to refine the higher end of the VE table and do some more R&D. I'll follow up with a full report on its performance on the track. Now that's going "Above and Beyond"

This video at VIR Grand East was taken with the previous setup/tune doing a few very conservative laps with new brake pads, tires, etc.. I expect my lap times at the end of this month at VIR Full Course to be quicker by approx. 10 seconds. You'll have a great experience out there

When do I get a ride in that animal?
Do I need a H.A.N.s device.
