Just goes to show that for making alot of power the LS3/L92 heads fall behind to the good ole cathedral port heads. Shows they have great flow numbers but can't perform the same.

Enjoy!!

Keep in mind Greg Good is very good at what he does and is one of the best porters and head guys around.

After looking up the vin I found out the engine is a LY5.

My question is where to start on getting more power out of this engine. Currently this truck only has a K&N drop in filter and a Flowmaster cat-back system. Where should I go from here as far as bolt ons or any tuning tips to get more power out of this engine?

My plans are:
Hooker long tube headers & Y pipe with my current flowmaster 40's series muffler, not a big flowmaster fan but if what im going to use now.

Maybe a Hypertech programmer and a MAC Cold Air Intake..

What would you suggest?

Even little things like removing mass air screen or any tips you know of would help...


Thanks alot,

What do you guys recommend as beginning steps to upping the HP?

I'd like to dyno it to get a baseline, but the engine is rated at 390HP with the automatic trans. I'm guessing its about 300RWHP.

I think my first performance mod will be a chip/controller, like HP Tuning.

Any "first mod" suggestions? ]]> Performance Modifications MaupinPhoto http://www.ls1truck.com/forums/performance-modifications/35190-first-mods-stock-ls2.html
