I have recently put together my 3S beams engine and dynoed and comparing to other dyno graphs online my engine appears to have a significant dip in low end torque below 3000. This is also apparent when driving as it feels sluggish.
The car is tuned using a maxxecu sport and the engine is a 5th gen black top beams (auto) with high compression 12.5:1 JE pistons and a 2.5in exhaust with vibrant ultra quiet resonator and street performance muffler. Car was tuned on 95ron octane gas. Currently only the intake vvti is tuned as the tuner indicated that no observable gains were made on wide open throttle with the exhaust vvti.
Is there anything that could be done to improve the low end torque or anything I should check?
