Default map sensor ?

i have a 97 sc300 with a 2jzgte swap single turbo upgrade. right now i have a corolla non turbo map sensor in right now

my question is im having a problem with full throttle/mid-high boost, its breaking up very bad like im not getting enough fuel. My wide band is reading rich (10.5-11.5) so i dont think its a fuel issue im wondering if its the map sensor not being a supra tt map sensor.

driving slow/normal i dont have any problems, in low boost i dont either.

also if it might be the map sensor will a EMS help out??? i have AEM v2 on the way and getting tuned next week.

ive heard i just need to get it tuned becasue im not getting enough air for the amount of fuel. also im running 660cc injectors with a apexi safc and if im not mistaken i think its usless with that big of a injector

thanks

check the Map... See if you can get a 3bar map sensor... Your Map sensor may be going hay wire because of the boost it is seeing...

corollas were not designed with manifold pressures higher than atmosphere, so it's probably not reading the extra manifold pressure caused from boost. Swap it out with a Supra Turbo map sensor or, if you're looking to crank up the boost later on, get a GM 3 bar as suggested and a tune for it.

I just swapped in a GM3 bar Map. I suggest you get Apexi's Map sensor because i think it is compatable with the SAFC2 I have a Power FC and i feel dumb that i got the GM3 bar but it works it just took me forever to figure out the settings and get it running correctly. PS i have a 1J not 2J but its all relative
