can anyone give me any info on tuning for the LZM stage 2 cams. i'm ordering those and hp tuners within the next month or so and just looking for any kind of info on them as far as tuning. flame on!!

I beleive the only problem you should have is Idle/ CEL light(maybe)

If you buy a Zeitronix wideband to replace your 02 sensor you can also change your narrowband switchpoint to accomodate your bigger cams...

i understand that but what i was looking for is suggestions on making my car run right with cams if that makes any since.

He wants to know how to tune for the the cams or what area's need to be addressed first.

And I am of no help since I dont have cams and Will be ordering HPT myself soon..
Have you read around the HPT forums yet ?

well with hpt you can prevent the cel's from coming onwith will solve any misfire problems you might have with large cams. You'll also want to lean it out a bit at idle, throw in a deree of timing and maybe even bump the idle rpm 50. Above 3400 you'll want to run a bit richer, although off the top of my head I can't tell you what afr to aim for to get peak power.

... since the car is now less efficient at low RPM, don’t you want to turn back fuel at lower RPM...........

tune to stay away from knock id suggest investing in a wideband and Id suggest bigger injectors people think im crazy when I say that but Id even suggest that as a first mod with hptuners since you'll come to find out how our injectors are already stock running pretty much on the limits of critical duty cycle.
