Did you have to shave the snout and if so how much to get the 2.38 to fit?

So what would you say a Good Lower to start with would be? And should the idler be done as well as a relocation bracket? I would like to do as many as possible before diving into the snout and upper. Also is it necessary to do a new Belt once you start doing them?
You can go up to 10% before you need to upgrade the injectors.

No Idle or relocation bracket is necessary.

When you go to 18% you will need the Idler Pulley and Injectors.

You can also go 22% with just the 50mm idler

When you go to the 27% you will need the Relocation bracket.

Each pulley needs a different belt.

The Rotofab Cai, SCT 3400 tuner The ATI superdamper with 10% Crank pulley, Belt, Crank Bolt, and JRE Custom Tune make up my 75 RWHP Tune package.

get an ATI lower with a 9.55" ring and be done. You must as stated upgrade fuel injectors and use an idler relocation bracket with the larger rings like the 9.55 or 10.

We have pulleys in stock ready to ship. If you do not want to get into a snout yet, I would do the lower first.

Any reason to go with the ATI vs the Metco other than price?

I'm confused...
This is my next upgrade (pulley's and injectors) and there are many opinions going around as what to go with. I currently have Pfadt headers, Roto-Fab CAI, and a ported LS7 throttle body. By reading through this thread, there are multiple ways to go. As Joe said, mine is my DD and I drive the crap out of it. I'm wanting to unleash more of the power this LSA has but not sure which direction to go.

Mine is getting the ATI lower with 22%, 50mm idler, ID850s and Kooks with green cats on Wednesday or Thursday. I'll post dyno numbers when she's done. I also daily drive the hell out of this thing

Awesome. Hoping to break 600.. But not a huge deal if not. I'll be adding a cam as soon as I figure out if I'm going to Germany or not. I'm not big on the idea of bringing a cammed ZL1 to Germany. Long way away if something goes wrong.

If you have the ability to Log your car you can gain that lost mileage back with a touch up of the tune.

Which injectors?

I know I am quoting an old post but since there are some new posts on it I am going to clarify.

What I had said is that when running the smaller 2.35 pulley you are more prone to belt slip. You will have less belt contact area and you are spinning it faster. Does this mean that you are guaranteed to have belt slip? NO. You are just more likely to have it with the smaller pulley than when you run a 2.55 pulley with the 10% overdriven lower (around the same overall percentage of overdrive, but you have more surface contact area).
