I put my PDR HX40 in last week along with the BD Stage V's. WOW what a difference. Now that I have over 300 miles on it. In the blink of an eye I hit my defueling mark 1,200 deg pre turbo. What do the rest of you guys do about getting around the EGT in less than 10 sec. ( go to the HX55) How can you race a 1/4 when it looks like the temp will hit 1,700 deg's by the time you get to the end. Well I do know that it does take some time to heat up a 3lb piston even though the top is 1,700 the rest is not. I have to run my box at 12% when it is on (anything over that and watch out EGT’S). So I can get my foot into it a little more. .<br><br>This is going to take some time to get right, I will need to do some experimenting with some of the fueling settings in the Blue Chip FMS along with the smoke control, timing box setting and defueling. I will keep up with the information to let you know what I have found out. OverFueled<br><br>
