IN first gear NO rpm shows boost although i can hear the turbo spool at about 1800. I ran first gear all the way to about 6800.
IN second gear i get boost showing at around 2300 rpm i guess.

my KF, KL-ZE, and KL-DE all showed no boost in first gear but once shifted to second it starts to build boost at around 2500. I've always used the bigger t3 from the ford murker and mustang svo. Maybe your wastegate is stuck open or somthing so you won't ever build boost. Try unpluging the vaccum line to the wastegate and test it to see if you will boost but don't step on it hard you might boost spike. Does you blow off valve go off??

My WG is tied shut already. I get boost in 2nd 3rd 4th and 5th..and yes the BOV goes off in thsoe gears. i get nothing in first.
And get this, i have the WG tied shut i can floor it to redline in 5th gear and never see over 8psi.
Also i get the most boost if i put the most load on the motor(makes sense) liek starting from a slow roll in 5th.or 4th thats when i an get to 8psi. but if i start from 1st gear, i get no boost in 1st ver little in second same with 3rd..maybe 4 psi in 4th and 6 ni 5th. I think its the WG on the turbo..maybe some cracks in the mold. OR i have a leak in the intake pipes..i used a ton of couples without the good T clamps. Tomorrow im going striaght from the turbo to the TB . ITs only about a foot or so long pipe that will do it. That shoudl rule out the intake side leaking.

Ok so i bypassed my mileoff pipes with the intercooler and it does get boost alot better. But i i still only register about half a PSI in first gear enough for BOV to work. I think by the time i get boost in first im choking it out since the turbo is wat to small for that motor. So either thats the case or i have leaky WG or both : P. Cause i made sure that the WG is shut and i cant get about to 8 psi and then i get no more after that..i think cause its choking...so ill use this for now then buy a biiger one.
Also theres some amount of oil in the charge pipes, so id say i just need to get a new turbo, this one has to last me till i save up 400 bucks or so.

Oil in charge pipes - I read (in this forum somewhere) that it could be due to a small/improper oil drain compared to the oil inlet. Basically more oil goes into the turbo than going out of the turbo - slows down the turbo too.

Naw i had this turbo sitting around the house for years, cost me 50 bucks. Just found out today one of my intake manifold bolts was stripped and loose, fixed that but have yet to drive it.

Hey X. It is sometimes common so not see boost or much of it in 1st gear. This is because the motor in not under much load. plus you are not realy in that gear long enough. The 1st time I experienced that. I started to roll in 1st, then I pull the e brake enough to slow the car down then gave in more gas. this but a load on the motor and I actually saw the boost. As long as its making the boost in the other gears you are fine.

Just another thought, but the exhaust side from the engine, if you have longer exhaust pipes to the turbo, it will take time for the turbo to spool. That will contribute to some lag. How larg are your exhaust runners to the turbo? If all the connections are tight and the w.g. is working like it should, the exhaust could be a possible problem.
