H/C tune results
H/C tune results I'll start off by saying I'm very disappointed and I know #'s don't mean sh*t, but this is extremely low. I made 400/390!!!! The tuner thinks the GMMG is choking up the set up. Prior to this with bolt ons I made 340/350. Thoughts?

I can tell you now, with that H/C combo there is NO way those #'s are accurate. That cam alone should put you at 400rwhp with stock heads.

This sounds a lot like my car on the dyno, but my traps at the track tell me that I'm actually making that extra 40-50 hp that the dyno didn't show. What does the tune look like?
What kind of dyno?
How far did you spin it to?
Any more specs on H/C? Those heads milled at all, stock gasket?
If you can post a graph it will tell us a lot more. What did you gap the TR6's at?
I agree the numbers seem a little low, but don't want to speculate without more info. I also agree that with LT's, ory, gmmg, you should not have any exhaust restrictions yet.

Yeah that exhaust should definitely not be a restriction much. Unless something is inherently wrong with the install or components of the head/cam setup, I'm thinking it might be more tune related. Mine was all out of wack (and by a very reputable shop to boot) and since the retune the car is very noticeably faster. I'll have new dyno numbers very soon to confirm, and it will be on the same dyno as well
Are the previous bolt-on numbers from the same dyno and on a similar type of day weather wise?
60rwhp doesn't seem to be *that* bad of a gain from a medium cam and ported heads especially if you still have the stock MAF in there. I'd look more at the gains on the dyno or trap speed rather than the final number on a piece of paper.

I'd expect more than that AJ especially with ported heads done by Ed. Something is definitely amiss.
What size Longtubes?
All time up stuff done?
Injectors new and clean?
Stock Maf?
I'd expect 450-470 with that H/C and a Fast added in a M6
My boy Adam has the SSHT with stock 243s and a Stock Fast 102 with a M6 and he put down like 429hp.

No, the previous #'s are from another shop/dyno.
Ryan, that's the same thing I'm thinking. Something is definitely not adding up here. LT's are 1 3/4, injectors are brand new, & yes MAF is stock.
Before you drive yourself nuts, check to make sure the tune is spot on and take it to a track to see what it traps. Till then, you're just pissing in the wind with guesses and random unachievable power expectations.
I thought the before and after was on the same dyno as well. In this case I agree with others on taking it to the track first. This will tell the true tale
