35 shot. tune needed?
Found a good deal on a lightly used dynotune setup. Was thinking about running just a small 35 shot. Do I need to get retuned and pull some timing? Or should I be ok? Planning on spraying pre blower. Current mods are 2.8, 60s and zzp tune. Soon to have dual pass and option b as soon as my gaskets get here.

Post blower is going to be more of a direct shot.
Pre blowers is going to put the No2 into the SC and there are debates on if this is good for the rotor coating (same goes for meth). It is also said that it will cool IAT2 temps some as well.
Regardless, I have always used a minimum of two nozzles and had them postioned in a way that the no2 had a straight path into the cyliners. On an LSJ I would do post blower with a nozzle on the 1-2 side and another on the 3-4 so there is little risk of cyliner pooling.

me either, I run a 100 wet shot on my g8 but I have timing pulled for it. I'd be real nervous running nitrous without a tune. Plus, these safe shots, would you even feel a 35 shot?

One of the motors was supercharged with a genIII eaton.
It blew up too.
Problem with doing any mofications to those cars was the shitty locked PCM. It was all very basic and not tunable. You had to rely on piggy backs, EIC's, or megasquirt SAEMS. But they were cheap, parts are plentiful, and the suspension I ran made it handle like it was on rails. It was quick on on the auto-x course.

I did. I got it down to about 125% running a 11.5 AFR at WOT and tuning in the MAF. My whole point was that people do no think about altitudes when they say "GM tune can handle this" or "LSJ can do that." Just because some one or some people do it, doesn't mean its necessarily right for the car. I had people telling me that the duty cycle I was running was fine actually. It all comes down to know what your car is actually doing before you start tossing more stuff at it. Thats why I was logging my car OEM Stage 2.
