I guess you are running stock injectors then? Stay out of the throttle period, if you hear it whining then let off you are into the throttle too much.

 

Yes stock flexfuel, I have the marine 8.1s that came with the kit but I was told my stock injectors should be enough. Depending on what it makes on the dyno I might go with a smaller pully and injectors later. I hooked the boost guage up to it today and I saw it jump to 4psi just giving it a little throttle hope I didnt hurt anything by doing that at least I know the blowers working right. I dont think the tuner gave it too much timing I told the tuner I was gona put some higher compresion heads on later then get the dyno tune so I think they just made it safe to drive with the cam until i was done moding and ready for the final dyno tune.

 

dont put on higher compression heads..boost dont like high compression...your stock injectors will peg out. you will need the 8.1 injectors, dont even waste yours or your tuners time with the stock injectors in there. injectors are not rated on dyno numbers

 

Stock flex fuel injectors are 38lb. and are fine for a stock 3.4" maggie pulley and 7 psi boost but ...not sure how much you can safely pulley down before maxing them out.

 

thats what i get for not reading everything

 

as said before DO NOT GO WOT with it maybe 40% throttle at most. OR start building a replacement engine. you WILL blow it on NA tune

 

FI motors need a richer fuel mixture at Wide open then a NA motor. Also I bet regardless there is TOO MUCH TIMING in the tune.

 

Twin Screw compressors don't get loud until they get into boost. The closer to atmospheric pressure the air gets to on the inlet side the louder it will be. If you really want to make a scene eliminate the cold air tubing. That comes at a price though - hot air from the engine bay. Super-heated intake air causes pre-ignition, so open-element filters should only be used if you have a capable intercooler setup.
Like others have said, it needs the tuning sorted out first.
