i just didnt know if it would make a difference to get a fuel pin or not since its at the deepest point and i dont have to wait for the fuel to get there, ya know what i mean?

oh it'll make a huge difference... the deepest setting of the stock pin isnt even close to the deepest point of the M&H pins, the stock pin has a gradual steady ramp up, M&H profiles are different and far more aggressive

You can see the difference here.

If I was to do it again I would go with a M&H M3 or M4. My DennyT stage 2 makes great power up top but fuels to hard down low and is hurting my spool up.

alright guys i have the bully dog pin, and i was thinking about getting the m and h m3 pin, is it worth the swap

tower_ofpower 03-01-2010 05:00 PM

i've heard of issues with the bully dog pin being too soft of a steel and the pin wearing a groover into the pin, so any hardened pin would be better at this point. i've got the M3 and i cant really complain, its got a power surge tho, it'd probably be less noticeable possibly eliminated with some AFC tuning, just i havent been able to get around to it.

I wouldn't buy a Dennyt. I just removed mine because it's deeply gouged after 4 months of occasional use. Certainly not hardened and he won't answer my email. I have pics if anyone cares. And yes it fuels too fast. I'm thinking an M3 this time.

I just got off the phone and everything worked out with DennyT. He had a bad batch of material get through and he is replacing mine with a pin with the correct hardness.

Wow. I'll have to check mine. I know he had an issue with some bad material and replaced a some for some other people. Keep trying him.

In all reality its not hurting anything.

so my question is do you drive every day with these fuel pins? i keep debating on buying one but am not sure. whats it do to you egt's?

SteveinAz 03-11-2010 07:19 AM

Everyday driving is no problem. Towing is smokey but heat is manageable. Just tune the afc to come in late.
