Corvette Nitrous Tuning

[Vettish]

Im driving a 99 vette m6 and am about to put a 100 shot or a 150 shot in (NX dry kit). Will the stock fuel injectors be sufficent for these shots? I am def. going to get some baselines to make sure the car isint running too lean. How much am I looking at to get it tuned correctly?

[Ed Blown Vert]

150 no way. I even think 100 would be too much. Can't you run it as a wet shot?

[Vettish]

What would be the problem? I watched a kid run a 00 vette (smaller injectors) last weekend a 100 shot (dry NX) just fine.

[Ed Blown Vert]

I don't know about a Vette, but the 99 f-bodies had smaller injectors. If you run out of injector you will run lean.

Just get it dynoed to check your AFR.

[Vettish]

How much do you think they would charge to tune it?

[Ed Blown Vert]

Probably a few hundred. Trouble is, since its a dry shot. Any tuning would screw up your N/A tune.

[Vettish]

Oh well hopefully the stock shit will be able to compensate for it so it wont be a problem. Anyone else know anything?

Well...I run a 100 wet shot and spent quite a lot of time researching this very subject...I have an 04 GTO by the way....have way too much money in it without blowing it up or doing damage over a 100 shot for sure......the concern with a dry shot is the MAF's ability to compensate for the burst very very quickly without allowing a very lean state for a few seconds while the computer adjust fuel to match the air flow.....many many testimonials about blowing/frying cylinder number 7 doing exactly this.....the other issue is pooling of fuel in your intake...kaboom.....dry shot is just fine if properly tuned...on the dyno.....If I recall correctly you have 42lb injectors stock...mebbe 38's....don't remember......your fuel pump should maintain 62lbs never any lower than 50lbs at WOT with the nitrous running.....you most definitely need a WOT Switch....Fuel Pressure Safety Switch.....Bottle Warmer...and I would put a Window Switch in there also.....never ever hit it when your bottle pressure is below 900......and never even attempt to install and run it without a dyno tune to make sure your good to go......I would seriously consider a wet shot......And by the way...I wouldn't dismiss ol Ed there so quickly....boy knows his shit for sure and is giving you sound/rational advise you solicited.....hope some of this helps you with your decisions...
