I have compounds HX35 over S471 7x12 injectors hot rodded VP44 with a fass. I just bought a quadzilla adrenaline what are the best daily and fuel saver tunes available 

I bought a Banks stinger plus directly from them back in 2005 and a Banks exhaust brake from a vendor. They worked fine for about 7 years then things started failing. I went to them for help and they bothered to give me the time of day. That soured me on them. 

As far as flow on a 24 valve I would have go with @Mopar1973Manand@Me78569and their opinion as I have heard that from here and other places. Thats on the stock 24v motor.

@@Mopar1973Man  so with having a hot rodded vp should I use the pump tap on the quadzilla

You can it not the hot rod pump fuel matters which it really doesn't it the fact that Hot Rod pump are advanced mechanically in timing. It the fact you 'll always have to calculate in that offset just like I've got to calculate the offset of timing because of the 320 bar injectors. This makes my timing late so I got to add more timing than normal. You will have to retard more than normal. Again its not the fuel part being it only an extra 21 HP you gaining. 

@Mopar1973Man so can you elaborate on how I can figure out how much timing I need to add or subtract. I'm new to this tuning

It's based off of watch engine load as you travel and engine oil temperature. High engine load means the the timing is not efficient or excessive drag. If you oil temp starts to creep up that mean there is more flame front on the cylinder walls heating the coolant and oil. Typically to advanced. Now you can advance timing by having washout injectors that are popped too low <300 bar. The more you get close to the actually desired timing the engine load will drop and the engine oil temp will drop. More energy is produced into work and less into coolant or oil heat. Any kind of excessive heat that is created is wasted energy that was not turning the tires.

@jagwhere did you see the difference 

Throughout from idle & up.

Dieselfuture, There is a little bit of a water passage at the back of the head on the bottom that needs a bit of die grinder. Other than that, just run Haisley .093 cross tubes. The head alone made a big difference in power. Lot more flow than stock VP.
