turbo experts 4agte

[reecegze]

Hey guys i am just wanting to know if this is a big turbo for 4agte. Ive got my t28 turbo hiflow to this and it seems to be very lagging ..I am leaning towards actuator is faulty but i am getting full boost at 6000rpm in 1st 5200rpm in 2nd/3rd so its seems weird when the suppiler rekons i should be full spooling by 4000rpm
Ive check for leaks and removed my MBC but its still not boosting properly.. I am using a stock 7psi t28 actuator that i put on with not knowing the condition before hand. It opens fine but might be opening under boost pressure to easy ? causing it to lag all the way to high boost

SO any info is appreciated
