Ok guys, so recently, in December, I installed my HPS SRI with my P2R TBS. I have noticed some things after the install aside from the "Tighten Fuel Cap" error message. After installing them both, I noticed my MGPs went down to about 29-31mpg from 34-35mpg; not too bad. While messing with the Fuel Cap issue with taking the TBS on and off to rid of the error message, it finally went off. I decided to take the TBS off semi-perminantly to see if the error mesage will come back on....BUT...I've now noticed with just the Short Ram Intake on and no TBS, my MPGs we down to about 19mpgs city and about 23-24mpgs highway and that is with the ECON button on with cruise control...
DISCUSS:
Are there any other R18'ers, or Si Owners, out there with an intake/TBS installed that have notice a dramatic change in their MPGs?
Why would I lose around 15mpgs with just an intake compared to the intake WITH the TBS?
Any insight is appreciated from you guys!
