I bought a set of 370 injectorrs from Rip Rook a bout three months ago and was very pleased with them even If my truck smoke less than it did with the 300 injectors A friend of mine came up with a set of PDR370's and I figured what the heck I would buy his and sell my injectors to another friend. The DPR370 are flowed or something so I just wanted to know if there was any diff between the two sets and since I was out time and no money I switched them. well heres what I found. The power might be up a bit maybe 10HP or so just enough to give it a little more kick. my EGT's are down 100* and ever time I let off the throttle my EGT guage goes right back to 100* which is the first # on the guage. with the 300 and my first set of 370's it would always hit 300 and stay there and slowely go down. does this mean the fuel is being burnt better or worse? ??? It just don't make sense to me but someone with a little more knowledge may know what is going on.
Thanks
