Well after a 5 week wait my psp chip and filter finally came. I put the filter on and ran the lightning and was not happy. I ran a 13.9 compared to 13.7 before the filter. Both times the speed was 104. These times were on a g tech on the same place on the road. The only thing I can think of is it was 0 degrees on the slow run with the filter and was about 35 degrees on the faster run with out psp filter. Anyone have any thoughts on this? One last thing I got a chevy sticker for the new psp metal tube that says 425 hp on it and the sticker lookes really good on there. Oh yeah I broke my bottom stock filter housing taking it off, anyone have one to sell?

 

Hey BP, Sal here. You really can't base your comments of a few G-tech readings. There are many variables that will effect ET. How was that barometric pressure for each run? How was the relative humidity for each run? It makes a difference. You can have close to a 3-4 tenth variance in you ETs just from weather. Now look at your MPH. You say you showed 104mph without the filter and still 104 with it, but with a slower ET. As a general rule, the higher your trap speed, the more hp you are making. So if you went slower for whatever reason with the same trap speed as before, then your making more power
