How does your C5 accelerate?
Good morning all. I have a question about how a 2000 (vert) should respond when you get on it. Should there be a smooth, uninterrupted acceleration, or does the C5 have some quirks? Mine came with Magna Flows and a K&N air filter and was recently given a tune up by a dealer (I know some of you hate dealers, but I bought a GM extended warranty.)
The reason I ask is because when I go full throttle in 1st or especially 2nd, I can feel a sort of "stepped" acceleration rather than a linear one. What're your thoughts?

And to the OP - My car is a '97 and when i'm putting along in 1st then step on it, I feel a linear pull of power... it doesn't really step. Just mashes me further and further in my seat... lol No VTEC in this bad boy...

Tune as in find someone that has a clue about tuning a C5 Corvette with LS1 Edit, HP Tuners or EFI Live and get your car tuned for maximum driveability plus power.
Tuning is still a black art - there is no "standard tune" you can just download and expect miracles.

p.s. Here is my latest VTEC sticker

Just curious, what did the dealer tune consist of? Just plugs and wires? De-carbon top clean? Fuel injector clean? Fuel filter?
It sounds like something is amiss with the engine performance diagnosis. Did a competent tech take it for a test drive?

Silly question, but do you have the traction control set to "competitive driving" or turned off? If not, that's make your car feel slower.
Good luck.

The tuners must had added turbos 
They have peaky acceleration curves due to turbo lags and boost spikes.
Kidding aside, mine acclerates smoothly and linearly. My motor is still stock compared to many of the guys around here.

I agree with others about getting a good tune. Check with clubs or with other forum members from your area on who the trusted tuners are close to you.

I'm not sure what you mean by stepped acceleration, but mine is basically stock and it pulls with smooth, almost electric motor smooth, acceleration in any gear. The Corsa Indys really start talking about 3500 rpm!
