small nitrous shot questions, those who know please...

[cobrakid]

hey guys,

I sprayed about a 85-90 wet shot the other week, and car went from
11.6@117 to 11.18@125.

...BUT, although I have 1 step colder iridium plugs, and 110 octane to be safe
car did something funky.....

I hit the manual button after car went about 5-6 ft.....
1.54 60ft.... shifted second, then started missing and put on CEL....
I held it the rest of the quarter shifting at about 7500......

When I got to return road, and made my turn....CEL off, and car was fine.
LIKE it just shocked the car/computer for a split second.

There was no stored code, and everything ran fine the rest of the day.

It did this twice, and 2nd time, I waited to hit it until 2nd gear.
went 11.30...@122.

I have a safe tune, BUT not a nitrous tune.

It was jetted for a 100hp shot, but due to bottle not real hot, and weather
not too great... I am calling it a 90 wet shot.

A/F ratio looked ok, on DASH while testing prior... never over 12.5s, so
I think it is ok. I am getting a NITROUS tune, but want to know
other than timing, what else is adjusted?

thanks....
