The dds3 is the control board for both the hfs1 and hfs5. The new kits use a different board setup all together. Yours will either have a low speed valve (hfs1) or a high speed valve (hfs5). The hfs 5 offers a proportional meth delivery following the injector duty cycle. The hfs1 is a on/off switch based on the duty cycle trigger point. Both ways work well. The hfs5 will change flow on the display gauge though depending on how much duty cycle your injectors have. The actual volume of meth your flowing depends on how many and what size nozzles your running, and also what system your running, so for the hfs 5, if you hit a max of 70% duty cycle, your only going to flow 70% of what the nozzles are rated for.

 

Kevin,
I think brian has the aquamist setup and activated the aux N2O map (timing and fuel). From what I remembered, its probably around 10% of the total fuel injectors since he took out 10% of fuel on the aux map.

 

KevinD in dallas is worth the drive. dont waste your time with anyone in austin. i live here, and wouldnt trust anyone here to tune my car. especially after Kevin hooked mine up last weekend. i have regular bolt ons, and he picked up 40hp and 60 ft lbs. this is on the same dyno as the OP.

 

Finally got the dyno sheet back. Also Kevin when could I get a chance to see the other car with a FP black in it?
