331 Dyno #'s Dead @ 5100 RPM (Long)

[Fox-4-Cobra]

I got the SCT tune and Dyno today. The engine died/choked off at 5200 RPM. The Dyno showed 246 HP @ 5100 and 297.5 TQ @ 3800.

The combo consist of a 331 SB (9.75 CR) GT-40 Irons (3 Angle Valve Job, Surfaced) 1.7 RR's, E-Cam, Shorty's, ORH and Flows. The rest is all factory as it came on the car (1994 Cobra).

I knew the stock TB, Mass Air Meter and Cobra intake would choke it some. I thought it would peak at 5500 and make another 30 RWHP. The wife and I are expecting so I wont be getting heads anytime soon.

Anybody have an opinion on what a larger Mass Air Meter and Throttle Body will do for the numbers? I know I'll have to get it retuned, to bad I did not get those parts before the tune although drivability was horrible. Happy with the TQ just want a little more HP. Anything I can do that wont affect the chip & tune to get a little more out of it?
