What was the difference in 2001 when the LS1 went from 305-310 hp? And if I had an 305 hp LS1 could I do the mod myself. I heard it has something to do with an removing an external "EGR" valve. Any input would be great, thanks.

I believe that the EGR tube/valve was removed from the intake... but this was because of a different cam profile. So, I believe the power increase occurred with the ever so slightly hotter cam (which also just so happened to allow for that EGR tube to be rid of).2002 Camaro SS 6 Spd<br />Sebring Silver Metallic<br />Still breaking it in<p>Traded in - 2002 V6 5 Spd Camaro.<p>\"I\'ll never trust squirrels again.\" -
They may have increased the overlap on the cam....I was reading a thing on the LT4, and that's what they did, it had enough overlap that it didn't need an external EGR system.Wife and a dog, they both think they\'re Kujo.<br /> <br />1999 3.8 A4 Y87<br />Navy Blue Metallic<br />BFG G-Force KDWS 275/40/17s, <br />WS6 Wheels (17x9)<br />Phoenix Transmissions 2400 Stall Converter<br />FRA, Holley Powershot filter, Whisper Lid, Ported Throttlebody<br />2000 manifolds, Flowmaster, WS6 Tail Pipes, <br />MSD 8.5mm Wires, MSD Coils, Autolite plugs<br />Performance Cryogenics treated rotors<br />1LE Sway Bars and panhard rod, 1LE front springs w/SLP Bilsteins, stock rear springs w/ 3rd Gen Bilsteins, BMR STB, KBDD SFCs, 1LE rear lower control arms, 1LE front lower control arms<p>1968 Chevelle Malibu 327 TH350Comment
