Hey All, First post. Long time lurker, couldn't post for the longest time. Snafu with original signup.

Hopefully my signature will show up below to tell what mods and truck I've got going. Basically Radix and Corsa cat back. More mods planned to pump it up even more and in preperation to them, I have a Transgo Shift Kit and Corvette Servo for 1-2 Shift sitting in the garage. My question is can I install these now with the Radix PCM tune or do I need to either tune TM out or purchase a tune with it gone before I install the Shift kit and servo?

I'm also planning on install a set of TOG headers but having a hard time finding any anywhere. I've been to TOG's sites and visited all suppliers websites but none list for an 03 Silverado. Where do I get them? Ceramic coating a must? I have found one set of titanium coated but have read that they must be ceramic coated to keep codes down.

Considering tuning myself. Pretty much decided on HPTuners and LM1 wideband O2. Am I headed in the right direction?

Some numbers based upon an Escort G-timer. Not been to the track. Best 0-60 w/4wd launches. 5.98 seconds. Best 1/4 -w/4wd launch 14.43@93.4 mph. Shifts really suck now. Gotta be costing me some ET. Hoping to get into the 13's. Planning on smaller SC pulley, Electric Fans, tuning and headers to get there. Nitrous is possibility in the future... wet system... which kit works with the Radix. Where is the fuel introduced?

Lots of questions I know guys and appreciate any input very much. This forum rocks!

 

Welcome

IMO you still have a lot more left in that Radix setup before you will need nitrous. Do all the basic mods that superchargers like and get some good tuning and see what you can wring out of the radix before you add the nitrous. I think you'll be happier with the kit that way. After that the nitrous will help a ton! There is a local guy in my area that went 13.8s@98mph in his Radix'd SS truck and he slapped a 50-75shot on it and is running 12.4s@108 now. I can't remmeber if he did anything else but I think that was it.

 

Where are you from BTW? I meant to ask because your MPH could be low because you live in higher elevation.

 

I know they cost a lil more but why not look into Arizona speed & marine L/T headers they are available at tbyrne motorsports. Sorry I cant help you on youre ?s. Im sure someone else will chime in soon that can. Oh yea I wouldnt install any washers with vette servo it will shift plenty hard without em. I hear its not good for the S/C

 

Central Ky. About 1000 ft ASL. Didn't calculate density altitude. Was low 90's and humid.

 

You can find TOG headers at Tbyrne motorsports. They are a sponsor of the site. Look for them over to the right.
