My car: 2k Firehawk, currently stock apart from an EFILive tune.

OK, I've started ordering parts, set of Pacesetter long tubes w/cated Y-pipe, plus SLP LS6 intake manifold. Still not sure what Cam to get ...

Personal requirements/wishes are decent street handling and similar efficiency (highway cruising @85 >30mpg) ... and of course better qtrmile performance

Original recommendation from a friend was to get a TR 224/244 .563/.563 114, another friend said I might run into trouble with inspection ...

Inspection being german TÜV , which means: not too loud/noisy, and specific things like exhaust values and motor values within certain specs (like, 600-850 idle, etc.)

I can get within certain emission specs if necessary by leaning the mix out (EFILive), though I was told I might need to raise idle to something like 1000-1100 on that Cam.

He suggested an Old Man cam (214/220 .600/.523 115), Cheatr also seems to be a nice choice (214/230 .601/.578 117).

Now, for next winter I might get me a set of heads, so I don't want to spoil any future "enhancements" with stuff I get now ...

What to do???

well the cheaTR is designed to work best with stock manifolds and exaust

How "bad" is the TR 224 on idle and emissions anyway? Got two different feedbacks, the one suggesting it said it was barely noticeable on idle, while the other said it would be very noticeable ...

I have the TR 224 (224/224 .563/.563 114LSA) in my car and it idles right around 1100rpm and tuning with LS1Edit.... with the exhaust running through the flowmaster I can barely hear it lope BUT if I open up the cutout it becomes alot more noticeable. It shakes the shifter alot and the car nicely.

The 112LSA will have a "larger" lope and produce the powerband in lower rpms. Where as the 114LSA has a less noticeable lope and a higher rpm powerband

We dont have emissions where i live anymore so I couldnt tell you there, hope that helps...

Should consider a Stealth cam (meaning with -6 overlap or more)

LPE- GT2-3
MTI- 220/220 115
MTI- 224/220 116
CheaTR- 214/230

Those fit the bill for more power and quietness.

I like the cheaTR for stealth.

I had the 224 .563 cam and it idled great at 750. So no problem there but....some of the others (steath cams) may be a little better for the overall restrictions.

Where are you in Germany? I'm at Spangdahlem right now. Damn I miss the Camaro over here. Autobahn with underpowered van rental sucks!!!!

Hmm, stock car means 3:42 ish and IF you have a M6 that would be 2k rpm at 80mph. Hmm, an agressive cam that gets 30mpg on highway? Not sure if it could be done. Agressive cams do not peak, become efficiant, until higher in the rpm's. You might have to take a bite in the mpg department.

That is just a general guesstimation.
