I have been driving my car after building the new engine (D15B VTEC) for awhile now and i feel that it has some problems, i feel it runs heavy and it shows itself more when i go uphill, it moves like snail and my FC sucks too! even worse than my fucked up engine. the car has an auto gearbox (i now it sucks!!!) so few time i had to put it in 1 or 2 so it get some power or turn off the A/C! (EACV also has some problems which i think i should change it!) i feel that there s a lot of pressure on engine without making enough power on wheels but when it get some speed it quickly become pretty fast.
