Insignia VXR tuning?
Discussion
Hello everyone,
I wanted to start an 'impartial' tuning thread, not linked to other sites that seem a little biased.
I have had my car for a year now and decided to start playing with it, after looking at just about every aspect of it over the months.
In a nut shell, what can be done WITHOUT throwing lots of money at this and swopping things that really don't need it.
I am getting the car Stg 1 Bluefin'ned' on Thursday. So i will post my findings on that early next week (Feedback seems 100% good).
I have also spent a weekend working on the airfilter housing and ducting to the front of the car. My car now has a sports air filter element fitted and the air filter housing has been cleaned up considerably, it also now terminates under the wheel arch and does not link up to the pipe that goes to behind the logo on the grille. The trianglular air box exit through the inner wing was belmouthed by hand.
The effect? well i didn't dyno the car before or after (Time sadly) but i did the work and then got the results flowed benched, my work and removing the pipework to the front of the car did see an 28% increase in air flow over the standard set up with the sports air filter.
On the road the car now makes a much more pleasant induction noise and it revs much more freely above 5000rpm, so given the cost, it seems a worth while mod to me. Also note the car uses the same air box and filter size as the smaller engined cars, so it really is a neglected area for work.
After the bluefin i am contemplating knocking out the middle exhaust silencer with a straight pipe. (I'm not convinced the system really needs to be swapped)
Lastly i would like to take the secondary cat off, but again i am being pushed into a Stg 2 upgrade and a replacement exhaust, but i can't really get an answer why this is a value for money upgrade. I am going to look into removing the cat and using a 4 wire MIL eliminator instead.
I am open to anyones ideas, tried and tested or theories.....

In a word 'Bluefin' don't do it, the product for the VXR is not fit for market.
It is riddled with faults, the car overboosted, held back and through up fault codes all over the place, despite three new maps being used. Statements like, i've put some figures in the throttle position map as there weren't any do not fill me as a customer with any faith what so ever.
Another point, when the car ran ok (Briefly) i ran it up a road i often drive, and yes it was quicker in the mid range (More boost), but tied up badly over 5500rpm, i timed the car with the standard map up the same road on 99 ron Shell and it was actually slghtly quicker. Food for thought!
Don't do it.
