Getting a Dyno tune (03 Cobra)

[GrowinupMX]

I'm getting my 03 Cobra tuned on a MD 1750 next week and had a few questions for others here. My mods are, C&L mass air,Mac prochamber, flowmaster catback, upper and lower pulleys (not sure what size they are). I have had the car about a month and all the mods were already on it. The tuner is saying i should see 440 to 455 rwhp and mostl likely need a Mafia. Does this sound right to you guys in the know and will this dyno (MD 1750) be a low reading dyno? Thanks for any input you guys can give.

Not sure how your tuner "knows" your predicted HP without knowing pulley size? I am unsure when a stock MAF is pegged on an 03/04?

Actually, I am not much help at all but post your numbers when you are done though as well as your pulley sizes.

its hard to say without knowing your pulley sizes. a lot of other factors come into play as well. Best way to find out is to just hop on a dyno and see for yourself.

Stock MAF pegs out around 500rwhp so unless you've got like a 2.93 upper/4lb lower or some variation that makes 15-17 lbs of boost, I don't think you will need a MAFia.

Thanks for the replies guys and I will post up pulley sizes and dyno numbers with A/F ratios when tuner updates me. I was told it put out 17# boost on a baseline pull but that's all I know at this time. Blower is not ported.
