D16z6 - T28 Turbo - Pump Gas Dyno Tune

This setup belongs to Chris from Rock Hill. He brought us the car for a dyno tune, but there were boost leak issues, along with a leaky head gasket before it went on the dyno. We installed a new head gasket, along with a set of ARP head studs, repaired the boost leaks, and got him back on the rollers to finish up the tune.



Here is the setup:

D16z6
Mild port and polished head
ARP Head Studs
Performer X Intake Manifold

RC 750cc Injectors
Walbro 255 LPH
Adjustable FPR
OmniPower 4 Bar MAP Sensor
MSD Coil
MSD Distributor Cap

Cast manifold
T28 Turbo w/ Internal wastegate
eBay FMIC
Greddy Type S BOV
2 1/2" Downpipe

Tuned on Crome Gold

Here are the results:

Boost pressure was fluctuating between 6.5 and 7.1 PSI. This is due to the internal wastegate.
