I had one, add a good set of headers and you should be close, do a cam and you will exceed your goals. Without spending alot of money there is not much more you could do. There is a Vette tax on most parts so expect to pay more for things then a comparable part for a honda.

Yeah, a cam and longtubes will wake that thing up like you would not believe.
I am also a fan of the Vararam CAI, as it adds a solid 2-3 mph in the 1/4 on an otherwise stock car.

Thanks

hey mike the guy with the monte told me to lean pe i lowered both the low one to -2 and the high one -3 better gas milage but a little sluggish when stepping down like at 30 mph at 120 02 sensor reads about 915 was at 935 at take off both at 905 when hitting the throttle what is a good number to have?

If it feels sluggish it may want a bit more timing or some fine adjustments to fueling.
PE is only at WOT, so I'm not sure how it would affect mileage.

Thanks

I have longtubes on my C-5, (2004) and it makes a big difference, but, if you don't want noise, Forget It!

I bought the LG Pro Longtube Street Header system, polished stainless steel to their x-over pipe, with the cats, to Borla Stingers with quad tips, Great system, beautiful sound! No clearance problems, but a little tricky to get the tips to line up properly. I get tired of hearing people say that they put on headers and now the car is louder, or they hear drone...for those people, Leave it stock! ....good luck....bob.
