What kind of dyno were you running on? For comparison sake RCZ put down something like 410WHP on a mustang dyno and than 455 on a dynojet, if memory serves, so there is a large difference between different dynos. Assuming all mustang dynos are the same, 420 on a mustang would be closer to 455-465 on a higher reading dynojet.

I have a 6 speed manual, also have a full exhaust hence the low boost numbers.

Yea Dynos are different I know, My tune and dyno was on local heartbreaker( Mustang Dyno). Funny this is there is lots of talk about my car , becasue of the AWD and being 7spd, an stock cats, but making such good numbers. but much props to Rob and kaizen Tuning,
How much was the upgraded MAF? IS it on there site or did you contact Sam.

I think the stock cats at this point are actually HELPING you create power due to helping you build boost though that is pretty awesome on an AWD automatic. Do you have a boost gauge? If so what are you hitting?

They are available on the site though you should be fine where you sit now, you can easily check what MAF voltage the car is seeing through any OBDII logger.

I think they were around $250 each, honestly I can't really remember at this point.
