Question Php tunes screwed up?

i got my ts burned through ktperformance with custom php tunes for my 160/80 stage 2's, i currently have a stock turbo and the first 2 tunes are for my current setup, the last 4 are for a gtp38r(whenever i get one). Fedex lost my package on the way back after 3 weeks of waiting already, then it took an aditional 5 weeks to finally get my package. I installed it and my truck goes pretty good but it should have more, it only builds 19-21 lbs no matter what on ANY setting and barley smokes even on the 38r settings, before my build with just a chip it built 26 lbs WTF! What should i do? Thanks.

either call kt or php about it.

it crossed my mind you might be defueling but your boost numbers are to low for that to even happen...
maybe check out the wastegate, i would do a couple runs with the red line unplugged and see what happens.(make sure you plug it after you take it off, i used a bolt on the IC clamp)

something def. isnt right though.

I used to have that issue and it crossed my mind too but I remembered hearing that php used the map for tuning and they dont delete it, but who knows. I haven't touched my turbo since it built 26 lbs before anything and ill try the red wire and see what happens. The only other thing I could think of is that the knob is broken and stuck in the first tune cause I cant really notice a difference in any other tune except slightly more black haze on the last tune, Thanks.

Also if i'm coasting down a hill in gear for over like 10ish seconds then push my clutch in to downshift or coast w/o being in gear my truck quickly dips below idle to like 500 rpm then comes back up, it has always done this, could that be inadequate icp? also if i am sitting in nutral and rev it at a steady 2000ish rpm then let off it slightly dips below idle too, like an obs with 300000k. But the trucks still very fast.

Contact Jay at PHP, I'm sure he can get it figured out for ya. My truck when it drops down too idle it dip's down to around 500rpm's then back up to the normal around 700rpm's but I don't feel any affects of it doing that.
