man, if you can open up the air inlet on the 80 series airbox to be 3 or 3.5 inches in diameter. Its the air intake choke point. I need to redo mine before i tune it again. Leaving a lot on the table with the factory sized intake hole coming off the side of the airbox can

I cut the top part off and 90 4 inch into it also make the inlet to the box bigger I can say first hand it makes a difference. @onemanarmy it also goes on the passenger side not driver side how you have your intake now.

@tmxmotorsports oh man thats what im talkin about! The LS1 i built right before i moved in the summer hit the dyno and the first thing the guy said was the airbox was restricting it super bad. What you did should clear it right up haha. Im planning on doing something similar to mine

I can't put that huge 80 air box on the passenger side due to the high mount AC compressor on my LS, and tons of wiring

is there a seperate check valve on the stock 62 setup?

Dang 70 bucks did you throw yours out?

 

[onemanarmy]

yea! $70!

i bought this truck with the swap done already....I guess they threw it out

on the hunt for a cheaper option!

but thanks....I see what the difference is with the boosters with check valves built in and the ones without (like mine)
