Message: [QUOTE="B585Ford, post: 444552, member: 5497"] I have a hand shaker and my mods are in my sig. After 10 PSI of boost, she is a perfect 1:1 up to a point. Often when cruising at 70-80 MPH, EBP will be less than boost by about 1-2 (when boost is 12 to 20). I have only ran the H&S tunes so far which may be a factor, but when I get to around 2500 RPM at WOT on a program rated 250+ HP, my EBPs start rising quickly (up to 70 [actual EBP] at 3000 RPM) so I have to let off. 4th gear is the worst, 5th gear can be a problem, 6th gear no problems (I assume because of lower RPMs - I rarely run my truck much over 100 MPH). For example, last night 5th gear, H&S 300 HD with LBF on 1, I hit 68 EBP at WOT when I let off and had in the high 40s of boost, a little later in 6th gear at WOT I hit 54 PSI boost with 64 EBP when I let off due to speed. On 160 HP or less, no issues with EBP. I still haven't ever hit 1350 EGTs (my defuel setting) after 7500 miles including about 1k miles of towing between 10-16k climbing many grades of 6-7% for a few miles at a time. EBPs are not an issue for me towing which I assume because I don't run high HP tunes when towing and I almost never floor it towing. [/QUOTE]
