Hi, had my car on a rolling road the other day to solve a misfireing problem and at the same time was checking out the power and it was really poor around 170 (not sure if wheel or flywheel whichever is lowest). Anyway the guy @ the rolling road place AVA in glasgow said it was because the car was too hot, it was @ 99 degrees. The car is a Sierra saph 4x4 and is meant to be stage 3. Ava's advice was to get rid of the air filter and put standard airbox back on and ditch the air con unit and get an rs500 intercooler?
Whats peoples opinions on going back to standard airbox? and wheres best to get a good intercooler?
Also the misfireing problem turned out to be the ignition amplifier so if anyone has a spare one im interested?
cheers
Greg
