No clue on this, I think you might already have a bigger heat Exchange search up what GM stage 2 came with.

what signature?

Injectors. Pulley. Belt. And tune. That's all. My car be reaching close to 190 while driving. 210 when stationary.

I sent this thru the Intranet™

That's a normal temperature.
You should be fine with the current heat exchanger unless there is something wrong with it.

what signature?

I noticed when its cooler say 140-160 car pulls harder and while up there in the 180-190 I start having some backfire

If you dont have a good heat exchanger I suggest the zzp stage 3 heat exchanger, I recently put it on and only took about an hour from start to finish. I have pics on here of it.
