I need your help gurus... so my sr20det blacktop just got a new t28 turbo and ran good while breaking in for a bit but I today I tried hard accel and from 2500 to 3000 I had power loss if cruising above 3k and id give it gas it responds perfect only when accelrating hard through 2.5k-3k range it would lose power. So I thought maybe it was my tps and I checked it...closed : constant v =5.20 tps at .48 and wot 5.11. So I thought maybe its off And i adjust the tps to a .45 while closed but not it reads 4.10 at wot. So I took it for a cruise and nowI have power throught the once powerless 2.5k-3k range but at a stoplighti idle at 2k wtf??? I slowly cruise it home putting it in neutral occasionally and still at 2k so when I get home I turn off the engine let it sit for a bit turn it on again and idle is down at 850 I tap the gas and it bumps ip to 1100 and stays there so basically I need opinions before I just throw money at this thing thanks for your help any input is appreciated.

They look Within spec. The wot voltage has to be under 5 v I believe
Also unplug the Ecu for a few minutes. Let it reset after the tps adjustment
