I have done a brief search, and couldn't find an exact answer. I am looking to do some minor modding to my car, and I'm not sure if I should burn my own chip or have one burnt for me.

I currently have a new 305 TBI, completely stock except for an edelbrock open air element. Here are the upgrades I am planning on doing (with the exception of suspension/chasis mods of course!):

Hooker 2055 Shorty Headers + Y Pipe
Hi Flow catalytic converter (not sure which one yet)
MSD Ignition System
3 in exhaust
Flowmaster 80 series muffler
new 700-R4 Transmission
4th Gen Rear
Hi Pressure Fuel Pump (not sure which model yet)

With just these upgrades, should I worry about burning my own chip?

 

Just raise your Fuel Pressure to 46lbs and call it a day. Unless your going to raise your compression or put a drastic cam in then you should be o.k. I would not hurt to start learning to do your own but if thats all your going to do to it then you really dont need to do anything.

 

I think 46 psi of fuel pressure is a tad high for a nearly stock TBI setup.

evil_dave, to be honest, yes, you should get into your own PROM burning. It is the only way to have it correct.

I do plan on learning how to burn my own prom chips eventually, but I'm leaving for boot camp (marines) in 20 days, so its not in my immediate future.

 

Sorry it was late and I thought he had TPI, yea 46 is a little much for that. And thanks for doing what you are about to do for this wonderful country, May god keep you safe. And good luck on the car.
