2004 WRX Wagon

Default My car seems faster on the 2nd pull..

04 WRX Wagon
-3" TBE
-K&N Typhoon CAI
-Walbro 255
The car was purchased with these parts on it.. It was Pro-Tuned by BYT Turbo (Sea Level) to 18psi and then drivin to denver (Mile High), timing belt skipped on last owner, I bought the car, Got the Heads rebuilt, and now I drive it. It runs great and feels quick, but if I do a pull and then a minute later do another pull, the 2nd pull feels much quicker. Is it just me "trippin" or could the ECM be correcting something or learning everytime? FYI: I put an AEM Wideband/Boost Failsafe guage in to monitor everything and under WOT it runs in Stoich or just a tad rich (Not sure of the #s at the moment). It hits 15psi and drops off to 12psi by redline. I havnt had it re-tuned yet, it is still on the old tune.

The car pulled a stock 05 STI multiple times by about a car and a friends Stage 2 STI Puts about 2 cars on it. (All done on a closed Road by NON-Professional drivers)
