Also SSilver is your car untuned?

It is suprisingly easy to port your own throttle body. I followed the well known writeup on this site that has been going around for awhile now and mine came out awesome. Spent about 9 hours over 3 days working on it. After installing it I could feel the better throttle response along with better pulling on the top end. It may have been all in my head, but ported tb's have shown nice power increases on the dyno @ ET. As to idle speed with the TR224, I originally had mine set at 850rpms stock M6 idle speed and while it loped and sounded awesome the car shook too much for being my DD. Uping it to 900rpms smoothes out the idle with no car shake and it still lopes pretty good. My idle is set at 950rpms with the AC running. Originally at 900rpms with the AC on it worked but seemed like the car was alot happier at 950rpms w AC on.
This reason I'm asking is I got a 02 Z06 cam for a 98 vette engine....still building.....ported heads.....Ls1 intake at the moment.....Total seal piston rings.....upgraded valve train to 918 springs, hardened pushrods, harland sharp rockers 1.7's and ti-retainers. This engine will be in a car weighing 2600Lbs. with 3.27 posi rear. Looking at 350 to 375 hp at the rear tires.
Your lucky for asking as I used to run a 02 LS6 cam b4 swapping to my TR224.. I made 376rwhp @ 361rwtq with the LS6 cam and 399rwhp @ 386 rwtq with the TR224. That's a 23rwhp @ 25rwtq gain over the LS6 cam at peak power. The area under the curve is what sets them apart. LS6 cam made only 8-12rwtq gains over the stock LS1 cam from 2500-4000rpms but above 4500rpms is where the LS6 cam makes it's power to 6500rpms. The TR224 provides more power than stock from 2500-6500rpms. Add an LS6 intake along with a 220 or 224 grind cam and you'll be scooting at 2600lbs.

Everyone who mentioned the ported TB, I just couldn't make up my mind prior to getting the tune. I read a few posts of people having trouble and decided against it. If I do it now, do I need a new tune?

Phil,
I wasn't going to use the titanium retainers if I had gone with the Comp 918's, but I decided to get the complete PP Gold Spring kit for $295 that came with titanium retainers and super 7 locks. I've broken 2 valve springs before on an older Camaro L82 engine. It had double springs and the loud ticking gave me plenty of warning that a spring was broken.
Thanks,
Glenn
