I bought a r32 gtr and always thought it was too laggy for stock turbos but after checking everything i could think of just decided thats how it was.
I bought a power fc, adjustable cam gears, boost controller and took it to a dyno tuner that was very highly recommended where he informs me that this is not normal so after a full day of him checking everything its making 200awkw on 12 psi which is apparently about right but it doesnt make full boost til after 5,500 rpm it just builds up slowly
Has anyone heard of this? cam timing has been down by the marks and the amount of teeth on the belt, no vacuum boost leaks, turbo actuators have heaps of pressure on them, i have inspected the compressor wheels on the turbos, swapped intercoolers, air filters arent restrictive, really the next thing is to inspect the exhaust wheels and the flaps to make sure they are sealing but because thats not a fun job i thought id see if anyone else has come across this problem and my tuner has never had this happen before
Standard turbos, standard manifolds (no exhaust leaks) im assuming just no brand stainless dump pipes the kind that seperate the wastegate from the exhaust and the plumb back in (which im not a fan of)
cheers
