I had to sell my last chipped ECU because I was going to go back to standard. But as the car gets closer and closer to being done, I am thinking maybe I should get another chip.

The last one I had was a PE chip, which was ok for like a stg1 car, but at the power I had there was a huge dip in power followed by a surge after 5300rpm, this was due to ignition timing on the chip.

Can anybody recommend a chip, maybe something with a linear ignition line? (I heard)

Thanks
