Nah, good tuning is whats kept it together so far. its making serious power. The threshold of maximum power has to be coming up shortly. I think in the future like any other car there will be the ppl that push stock blocks to 450-500 whp and then there will be the more conservative bunch who want them to live and be reliable who might fall into the 300-380 whp area. Who knows maybe the ecu is more powerful and is doing a better job.
