I've seen this too many times, in modding most of my cars I've owned.

You cant GUARANTEE any power gains, as every car is different. My could make 215bhp on the RR, yet someone elses could make 220bhp as standard. The other person has an instant headstart.

I have seen that there is obviously a very restrictive market for the mods on the crossfire, so after speaking to my local dealer, they are happy to warranty my car with a new exhaust, new engine management/chip and a new air intake system.

The intake is not far off complete, just waiting on the final measurements, then all will be revealed. RR time is being sorted this weekend, for a base run as I have now done the 1000 miles run in on the car. The intake will then be fitted afew weeks later and another RR sorted for power gains. Then chipped, again another RR done, then a new exhaust system then another RR.

With highflow sports cats, and new rear section from them through to a new rear muffler I would expect to see 250bhp without too many problems.

Lets just wait and see until someones done it !
