How much further til I need an IC

[CValiquette]

I'm looking at the gov spring and thinking of messing with my fuel pin or getting an ol smokey for my 91 non-ic. With the mods I have already (see signature), how much more do you think I can get away with before I'll need to fab up an IC system? Right now the truck stays below 1300 EGTs pulling up a hill. The truck rarely tows right now, mostly just street driving and bumming around the beach and the ranch.

I had a non IC 91 and you can see my signature for mods. Never saw EGT above 1250 even pushing it. My truck was a commuter, rarely towed or hauled anything worth mentioning, but I live in New England with much cooler temperatures.

At the hp level I was at the truck was nice to drive, and I never broke anything.
