Are you running both pipes right from the manifolds? and what did u do with the o2 sensors

[dixiemudnut]

@Sexymanye419 theres about 3 feet of pipe after the manifolds and then they come close together and share an 02 sensor, right after that was a dual inlet cat, i cut it off there and ran the pipes back, that way i didnt mess with the sensor and i have no check engine lites

@dixiemudnut here try performancechiptuning(.)com or an edgeproducts(.)com or even a bully dog good luck though

[joeyf504327]

@dixiemudnut well no, but i wasn't talking about a tuned chip, i was talking about tuned exhuast pipe length, the reason you lost power is because the exhuast pulses are out of sync with your engine, it should be as a pulse is leaving the tail pipe a cylinder opens its exhuast valve pushing the exhuast gases into the manifold, but at the same time the pulse that was leaving the pipe created a small vaume which pulls the gases out of the cylinder at the same time, if tuned you get a lot of pwer

@joeyf504327 im looking for a chip now, kno anybody that makes one for a 91 351w 5speed ford?

[joeyf504327]

@dixiemudnut thats because its not tuned for your engine, if you got tuned straight pipe your mileage, torque, and hp would go up : )
