How often do you wish your half ton had a 6.6L in it?

We swapped a L8T 6.6 crate engine with the Brian Tooley Racing 225 camshaft in this one, sounds killer, great mid range and top end power.

If you did a stock LS or LT conversion, does a full Dyno tune come to mind?

The answer should be absolutely. You never know how much you are leaving on the table, even if it’s a stock 5.3L gen 3 LS on 87octane.

Nothing like starting a Monday with the Spicy fuels on the Dyno 😂

These BluePrint Engines Manguson 2650 equipped 427 LS are stout, 703rwhp 93 through a 4l80.

Look at this guy bringing us the worlds cheapest Zo6, at a purchase price of $3000 and then had the 🥜 to drive it 10hrs here on his way home.

HOW MUCH POWER DOES A STOCK 2001 Z06 MAKE ???

The only thing done to it is a crack back exhaust

Pre tune Hp ??

Post tune Hp ???

I’d say this has to be the lightest and smallest LS converted car I have tuned. That’s even considering some Exocets. 🤣

Finally! C8 TCM tuning is rolling out.

Another Thursday, wrapping up another cam swap.

6.6L gas engine, 87 octane, Stock vs Tuned, nice gain for a tow rig.

Do you have a tune on your gas tow rig? 6.0, 6.6, and 8.1 always have low end torque left on the table over GMs factory programming.

Oof, drove a little too long on this one 😬
