Coils don't "wear out" or get weaker with time and/or use. They may go bad and stop working altogether but they either work or they don’t, there’s no in between. It’s an electrical component with no moving parts, nothing to wear out resulting in reduced performance.
A functioning old coil will perform exactly as it did when it was new.
The gains shown here are similar to what I had in a rough dyno run as well as what others's who've done the swap have said about driveability and performance "feel"

I'm sold... eerrrrr, I was sold, and currently have the truck coils.
Just watch this video:

He specifically spells out the difference in power that the truck coils deliver compaired to the ls1 coils. Fact is, when you start to bump up the compression and load on a motor, you will benefit from a stronger spark. Why do you think GM replaced the coils when the ls2 was introduced, and once again when the ls7 and ls9 were introduced. GM doesn't spend money switching things for no reason. Fact is, trucks experience very high loads on their engines when towing, and trying to push around 6,000+ lbs, so they needed a higher energy coil. GM saw the benefit, and integrated similar performing coils on the ls2, ls7, ls9.
This is the second dyno that proves they work.

1-what years and engines can be used? 5.3 and 6.0? 2000-2006?
2-is it a direct fit and plug and play?
3-retune needed? or it will just give a stronger spark and that`s it?
thanks for sharing and waiting for the info thanks for that too if these questions are answered maybe more people will post results of this swap

nothing was changed. just swapped the coils.
to answer a few other questions.....
Its basically a plug and play swap. There was some minor drilling needed on the truck coil bracket to make it fit....but very minor.
No retune was needed.
I do not know what year truck coils they were. The customer brought them in with him. We did not provide them.
The car is a stock cube, bolt on car with a cam, long tubes, FAST 90 intake, 90mm TB, 243 heads with mild port work, A4, stall, 9 inch.
