I have done 26 on 450's with a wally 255 fuel pump gm maf and maft, if you have no tuning devices the easy way would be to buy a 2g maf and 550's and they will balance out pretty well with no tuning and will be able to do 20. another thing is it depends on your turbo if it can even boost 20+ psi i was using a small 16g then. im not to familiar with the 14b.

Well it popped after 2 weeks of daily abuse so i dont recommend doin what i did i just was testing how far i could get on my setup. all i had was e3 s16g full 3 inch turbo back exhaust a gm maf with maft, stock fpr fully stock block besides 2g pistons, walbro 255 rewired, and a 30 psi boost gauge that was it. i had a glow shift crappy boost gauge but i was sure it was malfunctioning but then i got a autometer 30 psi gauge and it was still the same. very surprising to me it pulled it off but it didnt last its the red car in my gallery pics.

whats the fp rewire for?? whats the difference from a maf and a maft. and i have a adjustable fpr autometer gauges walbro 255 fp pace setter manifold megan turbo 02 housing

The fp re-wire is to supply more power current to the fuel pump that that small stock wire cant, some people do it some dont. the maf is the mass air flow sensor from a GM car and a maft is a mass air flow translator that converts the gm signal so the dsm ecu can read it. it also is used for minor tuning and also does not have maf overun like a stock maf does it can do 30+ boost and the maft has a fuel cut defensor, 750s should get you to 20 psi or more with link and 16g turbo.

here is some more from AFI Mitsubishi DSM by Advanced Fuel Injection not too expensive.

thanks so much for the info im a honda guy so dsms are like sticking me into a womens bathroom idk what to do ...now withe the gm maf is that better than the 2g maf ### i just bought a 2g to1g maf harness so i can run the 2g maf plug and play

also should i just go big now in case i want more boost later ? 1000cc injectors???
