How hard do you think it would be??
 

I've been tossing around the idea of swapping my truck from TBI to TPI for the past couple of days. Would there be any gains in performance from this and how hard would it be to do it?

more torque and a little better mileage probably.....

personally, having worked with tpi before...my choice would be NO.

no one tunes them anymore, and the obdi controls are archaic. save your money and go to a fuel injected ls drivetrain when you put the money together. you'll be much happier, take it from someone who swapped from a tpi to a 6.0l ls!
