01ws-six

Hey guys, Wondering if anybody here can help me out for a minute?

I have an 01 WS6, mild cam, slp headers, 373 gear, lid and ls6 intake.

It was never properly tuned when I bought it, my brother who is an amateur tuner got it running decent with a rough tune with hp tuners but it still has some issues that it needs worked out. It surges at idle when ever you put down the clutch, ie coming to a stop.

I was wondering, does anybody know of any good tuning shops in Ontario?

I heard of one called cdnperf in Toronto, but cant actually find their website?

If someone could give some advice on the idle surges for the meantime until I get it tuned at a shop, I would be very grateful? Im not really looking to get the most powerful tune possible, just one to make the car run excellent, I dont plan on doing any racing.

Any input is appreciated.

Thanks!
