in fact if yur secondaries are jammed open it causes a severe drop in lowdown torque as the engine is not running properly

what normally happens is the engine runs normally untill yu hit a certain rev amount (as potsed earlier approx 3700 rpm) and then this actuates a mechanism to open a second inlet system (laymans terms yu suddenly have an extra set of lungs)

more air is being pumped into the engine so the ECU pumps more fuel which mean bigger bangs = MORE POWER (GRUNT GRUNT)

however if like me yu are having problems with yur secondaries not openeing yur car will get to approximate 5000 revs and stop there as there is not enough air / fuel mixture to continue (in top gear) however and back to my original point if yur (like me) jam your secondaries open yu regain your top end at the expense of bottom end torque

so the choice is yours

the reason why i am going on about this well yur 2ndaries may be jammed open but the actuator could look like it's closed

this could be an easy solution!
