[QUOTE="superpsd, post: 1543402, member: 15821"] First of all you went from split shot injectors to single shots. Single shots may smoke a little more on a cold start. Yes many injector builders cut corners they use shims and some likely use low end parts to increase profits. Bran new injectors vs remans no matter what size new is a better choice. Not sure how much smoke your seeing. Some cold haze is normal. My 200% nozzles barely haze down to freezing temps. I am running B codes with higher VOP than a A code/hybrid. Tuning can help. Changing nozzle size effects SOI and atomization at lower ICP like at idle. Some adjustment to PW, ICP, SOI and the multipliers can help cold haze. Tuning is an art in dome ways. Changing one parameter can effect something else. For example increasing ICP will advance timing. Installing a larger nozzle without changing anything will advance timing, higher VOP will retard timing etc etc. This is my 7.3 idling on a cold engine 200% nozzles at 400 rpm.
