my car made 270bhp today,it a c20let with bigger intercooler,15psi boost,ph2 superchips,does this sound about right?
also what gear should it be yested in?mine was done in 5th.
he said that the turbo comes in late,it won't make decent power untill after 4k but then it shoots up,anyone else had this?

5th gear? 3rd or 4th is more suitable. running in 5th the acceleration rate willbe very slow so unless they change the RR ramp rate to match the turbo will come in very late!
turbo'd cars should be run with a much faster acceleratio/ramp rate than a n/a car otherwise it wont boost as it would on the road, it would be like sitting at 1000 rpm in 5th and flooring it, it would take ages to pick up and boost will be delayed until the engine speed overcomes the dyno's inertia.
( I did a course once on dyno operation)
