LGT dyno tuning, 09 WRX installs
Perry’s LGT retune went well. The Dom3R with 10cm housing couldn’t match the spoolup of the FP Green with 7cm housing, but it did make some extra horsepower. He’s going to check over some of his work and we’ll revisit this soon.
While I was tuning our mechanics were tag teaming Darrell’s 09 WRX.
They installed:
KS Tech 83mm CAI
GS 3 port boost control solenoid
DW 650cc injectors
Defi Red Racer boost gauge
turbo blanket
After installs:
The car already had a Perrin TMIC, GT Spec header, walbro pump, and upgraded turbo back exhaust.
After the installs we got the car on the dyno and I started tuning the new intake in. When I started getting into boost I noticed spool up was a bit lazy, but I thought it might just be the header with big primaries. Then I did a full pull and noticed both spool and power were lower than expected. It was getting late, but we stuck around to sort it out and we’re glad we did because the power the car made in the end was great. We rigged up our smoke tester to the intake and found a hose off the turbo inlet was leaking heavily at a union fitting. After clamping the connection we retested the system and found no leaks. After hooking the intake back up I did a pull with no changes to the tune. Spoolup was better, the car picked up 40 ft/lbs of torque, and I had to cut the pull short because it was trending lean due to the change in airflow. After dialing it in, here was the result for the 93 octane pump gas tune:
Our mechanics also put an 07 STI turbo on an 04 WRX and will be finishing installing an APS TMIC and FIC injectors in the morning. Then it’s going on the dyno.
