Why do you think it needs new wastegate springs? I highly doubt those are worn out.
My guess is that you over boosting? If that's the case, you have a vacuum/boost line leak. That problem plagued me for a couple of years...turns out it was a stuck EGR valve.

Was told originally with the true dual exhaust that would need red spring installed. now, per email from Scott Rawlings that i just need to back off the preload screws.

How far do they suggest backing off? To a certain boost level?

If everything is in good order you can safely 56-58"hg with no worries.
If you are overboosting after backing out the wastegate screws, start a new thread and we will help you thru it.

Worth mentioning, Corvette Center in Newington, CT which is operated by Ray Zisa, is a fine choice in servicing classic Callaway vehicles.
Corvette Center did installations of many AeroBody packages in the 80s and 90s, and Ray has served as a Bloomington Gold Division Director and Judge for decades. He KNOWS Corvettes and Callaways. Check them out:

Great topic...would anyone know of a trustworthy shop pithing a day's haul of Omaha, NE.? As near as I can tell thus far, DRM up near the Twin Cities is the best option for us central plains folks.

I am in the Charlotte NC area. Does anyone have a suggestion for diagnostic shops? I have an 88 CTTC that is overheating from a fan (that is working) but not being called to come on at temp. Relays all check out and the fan can be jumped to spin but at 245 i feel it should be kicking on but there is nothing.
Thanks.
