Stumbling Problem When Upshifting
My C5 has some issues going from 1st to 2 second on WOT. I get it up to 5500-6000 in 1st, then when I get her into 2nd, she falls flat on her face. It lasts about 2 seconds, then the motor picks up again. The motor doesn't stall, but the loss of power always puts my face into the steering wheel.
98 C5, heads, cam, nitrous, long tubes, and every bolt on your can think of. She dynoed at 516rwhp with nitrous, which to is kinda low to me. I had a tuner slap on the 200 shot wet kit. I thought he was going tune it as well, but when I picked it up, he said it was already tuned, so he didn't do it. Aren't you supposed to re-tune after a nitrous install? This is my first nitrous car. Please keep in mind, that this event occurs with the nitrous unarmed. The internals are forged.
Here is what the previous owner gave me:
The previous owner left a few things out. He wasn't good about a spec sheet.
I'm ready to race, but 'can't seem to wrap my head around this.
I would gladly welcome any theories, thanks!

Problem gone!!! I was elated! Not only that, the C5 is definitely snappier. She feels like she was sprung! Also, Ronnie gave me some cash back after I paid in cash.
I LOVE HAPPY ENDINGS!
PS: N20 bottle is full. I hope the motor doesn't get all blowed up!
