dyno graphs
post them if you got them! tell us what you have done. even more so if the dyno was done after just a few parts to help narrow down what parts add what power. this should benefit a lot of ppl and maybe even answer some future questions

PIcked up 31 HP from the tune motor had 500 miles but had a miss (The blank part a little over 4K) because of a bad opti. Opti has been replace and I corected a huge exhaust leak so I am hoping for 420+ next time I get some tune work done

These runs were done with the mods in my sig...basically K&N and full exhuast.
Notice the 2 "blips" in the upper RPM range - that was the first two runs. It got smaller with each run, and by the third it was basically gone. The tech thought is was knock retard, but I dunno...

Your basic LT1 top end kit here
The first run in 2003 is with the heads/cam work but still running the stock cast iron manifolds and old exhaust.
The second run is with the heads/cam and now TPIS headers and full 3 inch exhaust behind it letting it breath. Notice how much the torque is improved with max exhaust breathing. A heads/cam can't do its thing if the exhaust is choking.
The run not yet done is after getting my TB bored to 52mm to open the intake some. But I'm scheduled for Monday and this weekend it's going to snow. So probably not going to do it.

Pretty impressive gains from exhaust work....45.7 ft-lbs & 36.4 hp!!!!!
You must have raised the rev limiter from 5800 to 6300

Raised the rev limiter to 6400.
I'm hoping the 52mm helps it above 5800 rpm, so it doesn't drop off so drastically at 6200.
