guys with well-tuned minirams
Can I see what A/F ratios you're running in your PE tables?
Also, what your cam and heads are to put in context.
I've been getting a little more top end power out of my combo as of late with some more tuning, but it's making the idle to 2500 rpm seem a little disproportionately soft (and not really responding well to my changes as compared to the top end). I think it has more potential than what it's currently delivering in that rpm range...
I'm just curious to see what A/F ratio Minirams like to see in that rpm range.

Re: guys with well-tuned minirams
Anyone?
I'm really curious to see what's working for folks (PE, AE, etc) compared to what's working for me and what I've been learning about.

Re: guys with well-tuned minirams
If you can get a hold of the owner of Firehawk #26 (I believe he is a member of the forum) that may help. It has a TPiS Miniram that was re-custom tuned in around 2002 in the LA/San Bernardino area by the owner at the time whom I knew. It ran MUCH better after the modern custom dyno tune. Perhaps the current owner can get you a dump of the bin.

Re: guys with well-tuned minirams
I'm running 12.5 tapered down to 12.2 after peak torque. My car picked up a couple mph in the 1/8 mile doing this. Rather than leaving it at 12.5. Heads are afr 220 competition port cam is zzx, 420ci

Re: guys with well-tuned minirams
Interesting you went richer after torque peak rather than leaner.

Re: guys with well-tuned minirams
When I race it never drops below peak torque after the launch. It may like to be richer across the board but I haven't tried it.

The LT-5 torque peak is ~ 5300rpm and HP peaks at ~ 6800rpm. I go from 12.5-6 AFR torque peak to 13:1 for the power peak.
