All mods on this heat soaked run #6 of the day. SW 1 7/8 LT's, Cat delete, 3" Magnaflow comp catback, CAI Inc intake, Vmax TB & tune. 83 degrees and 29% humidity with a tiny busted up house fan on a bucket (large bay fan broke right before me)

Here's my dyno sheet. L99 with shorties and hi flo cats along with dyno tune. 374 was the final run after the tune was complete.

What i do have however is a Camaro that sounds like it should.

Lol that's what I'm talking bout!

Just to muddy the water a little. Lol. Your numbers are on a mustang jet. They always post lower than dyno jets. Usually about 10% lower. Nothing wrong just different machines calculate different.

It's a happy dyno, that's all. To do it right and build a good foundation for future builds 1 7/8's or 2" Lt's are you best bet, that way you don't spend more money later. Lt's will always outflow and outperform the shorties. No if's and's or butt's.

it doesnt matter what his dyno pull was. LT's are proven to have far more gains than shorties.

simple google search will show you the light.

I never said they didn't. If u read my post, It actually goes with wut your saying. Except I said if you don't plan on doing future mods(cams,ect) then shorties may work for you. Im by no means a gear head. I just love the way the camaro looks and wanted to make it a bit more fun to drive. My post was not meant to be a debate
