Hey i was thinking of buying a chip for 150 bucks it is going to give me 20-30 more hp. I have a 305tbi do you think this is a good buy?
thanks

There is no off-the-shelf chip that is going to give you 20-30 hp on a stock engine.

I have dyno tuned 400+ horsepower tuned port engines that only gain 10-15 horsepower at the wheels.

If you really want an aftermarket chip, you need to get one custom made to your car, either by yourself, or by someone reading what your car needs with a scan tool and doing it on the car. Its practically impossible to tune a car over the internet.

In the meantime, turning your distributor up from the stock 0 degrees initial advance to about 6 or 8 degrees initial will really wake it up. The TBI computer program has very little timing in it to start with.

 

Thanks and my dad a 69 mustang with the clevland he advanced the timming on that would it be the same way? Then also i have tbi now that is some what like a carb right i was wanting to give it more gas like by turning screws on a carb is it the same way on a tbi?
thanks

No there are no screws to turn on a TBI to give it more gasoline. Its all controlled by the computer. You can get a vacumm controlled fuel pressure regulator from http://www.top-downsolutions.com/ that will let you adjust the fuel a little bit.
