I have a 1999 with a DTT transmission -275rv injectors -practical solutions boost module- RASP and fuel pressure gauge. No other gauges. I had a VA box but it went bad and I think it took out the VP44 ??? Anyway I need to get 50- 65 hp back but not at the expense of another vp44. My transmission was built for 300 hp and and it might be nice to have gauges but I could live without them as I do not tow very heavy. Do you think I can run a EZ without gauges as I did the VA or go the money and get the Edge juice. I want reliablity of the VP 44 as the number one priority. Boy do I miss the extra 50 hp of the VA. You get used to it then your truck feels like a dog. Give me your wisdom please,Thanks!!
