i have a 305 tpi and its bone stock with a hypertech chip. i have a bbk 52 mm throttlebody, headers, 22lb 350 injectors, a set of underdrive pullys, and some roller rockers sittin around. im planning on bolting them all on very soon and i was just wondering if i needed to do something with the computer or if the hypertech chip will work with all the mods

 

pcmforless.com

 

so im going to need to change the computer chip??

 

The hypertech is kinda crappy to be honest.. It just adds a bit of timing when flooring it. But why the 22lbs injectors and 52mm TB? Those are not needed on a bone stock 305... I have 19lbs injectors and 48mm TB (both stock) and my 305 (not stock at all) makes tons of power.

 

well i have em and i just want to pep it up a lil with what i got and i figured a stock chip would b better than the hypertech

 

any thoughts if i have to change the computer for the injectors and throttlebody

 

You'r car will run fine without the tune, but should you decide to just know I picked up 20 hp with my PCMFORLESS tune. Its $200 and all you do is plug in a small chip to the ECM.

 

For the throttle body no because that is just more air flowing into the engine which the ECM will be able to adjust by itself since it just a small change.

For the injectors, you will need to change the value from 19lbs to 22lbs (if you are going from 19lbs to 22lbs, which I assume you are since a 305 TPI has 19lbs injectors stock). This is simple if you have PROM burning equipment. It should take a few minutes to do and the computer will then know that the injectors are 22 and not think that the 22's are 19's and spray more fuel for nothing (probably giving you a rich condition).
