THat's a lotta' boost there Steve...

What's in the chip?

My second ship from Marc was only for 2nd deletion, I think. I could tell I was getting a little more twist; I'm guessing about 20 - 22? Maybe as much as 45 dB

Had a Mark H chip, sent it back to be modified for exhaust work. Recently dyno'd again at 397 RWHP.

Ok - this is interesting here...

I don't remember if I told him that I was doing new pipes.

Do I need to send it back to him? Anyone know if he keep logs of chip-work / chip ID's?

Did you send it to him after you installed your OBXs?

He also changes if you pull the cats out. Let him know.

No - he had it when I did the top end housecleanin', and it was for 2nd deletion. I said 'sometime' I would do the pipes, because he had asked about airflow mods.

I don't know if these psuedo-cats count for very much - I'm sure they're not for looks (or ARE they??? ), although Jeff [Shrek] wanted the new ones I got with the OBX, since he had given me his that were sewed up onto the X-section.................

I'll have to ring him soon here.

Yep, those bullets that come with the OBX are just for looks, they're not cats at all. I guess they're meant to help with a visual inspection in states where that matters.

You should definitely send the PROM back to Marc. When you do headers, he adds fuel to support them and enables the anti-backfire. Until you do this, you won't produce all the power that adding headers allows. Marc does keep excellent records; that's how he was able to figure out that he hadn't enabled anti-backfire on mine without even having it in his hands.

Glad the OBX came with the psuedo cats, in NH all we need is a visual inspection and the check engine light can't be on.
