My Astra VXR only made 215 on the Dyno and by looking at the graph, it looks like it's being held back around the 3500 range.

The car only has a pre-cat delete, Cobra cat back system and a crossover delete with AEM cone.

The standard bhp is 236bhp but mine is only peaking at 215bhp
The standard Torque in NM is 320 but mine is up at 376.

I find it odd that the torque is up but bhp is down.

I've done the following:

  • Checked the actuator is opening at 10psi
  • Smoke test carried out - no boost leaks
  • Replaced Map sensor
  • Cleaned MAF
  • Replaced front Boost Solenoid
  • Checked all vac pipes and ensured all pipes connected at the rear of the vac box
  • Replaced coilpack

I've been trying to figure this out for a while, I did notice after changing the coilpack the car is running better and a slight improvement in the car being more aggressive as it was when I got it.

I've tried to narrow it down as much as I can but is there anything else anyone can maybe advise me on?

Also, the code 110611 popped up after the Dyno, reason being why I replaced the MAP sensor but after clearing the codes the code hasn't come back.

Thanks all
