The way I look at it is on a turbo'd car, any nitrous you put on it is doubled.... For example, with a 25 shot you would not only get the 25 extra horsepower from the nitrous itself, but also drastically cooler intake temperatures and better combustion of the pressurized intake charge PLUS you have the added bonus of faster spool.... I have seen boosted cars with a 35 shot and some tuning gain about 75 wheel horsepower... It makes a significant difference on a boosted car but personally, i would go for the wet shot and get it tuned.... hate to hit full boost and be on the bottle and lean out... talk about detonation, ouch, that H22 would be toast, kiss that bitch goodbye.... Just my thoughts...
