Which injectors do you recommend? I'm in need of injectors. I'm cam'd and have a lot of bolt on's. No heads yet. No NOS either. I was looking at the TSP 42# injectors. They seem like a decent price. Anyone have some recommendations?

Assuming a 45% BSFC (500hp x .45)/(8*.8) = 35.1
Not sure what a H/C LS1 qualifies as for BSFC, but you can see that in some cases a 30# SVO (36lb) won't be enough. Also, you can get flow matched 42's on fleabay for $280 shipped (I just ordered a set) so they're just as cheap or cheaper than 30's!!!

The rest of my tune is pretty close to perfect. I have spent hours trying to dial it in the stated problem areas. I have gotten it to where it feels like a vibration but I want it puuuuurfect. I think that the problem must be in the injectors min pulse. I hear that these Motrons wont go below 1.5 and I have never seen mine drop below 1.7. I have zeroed out the adder table and have the min set to .5 and nothing. I have tried many settings inbetween also.
I have made changes to all of the air flow tables as well.
