SO I've just added an S5 TII motor tranny and all the neccessary add on to handle all this in my 79 sa and it's working out really well but i'm haveing a problem with my boost. I'm fine through low boost/non boost low rpms but once i step on it i get heavy hesitation,backfireing-so switching to the next gear lets it go but it happens again once i hit the 4500=4600 rpm range.

spec: jdm TII 90 13b, tranny
3" all the way
stock ecu which i think is fucked up
still have the afm map sensor all 370 and is the proper model #i'm suppose to run
took out the smog stuff plugged up

if you guys any help coolllll

 

o yeh so i forgot what i was originally posting for im looknig for an ecu. So I've heard that haltechs are the ****. I've got 600 saturday and i'm going shopping on monday. If anyone knows of anyone that has a perfectly working ecu thats for sale i would like to know whats up on the sale. thanks

 

Sounds like secondary fuel injectors are not firing...

First, this thread doesn't belong in here.
Second, if you can't trouble-shoot basic problems like that, going Haltech is not something I would recommend to you.

Fuel Injectors Are Not Working Properly I Had The Same Problem Sent Them Out To Get Re-done Cleaned And All That Good Stuff Got Them Back And They Work Just Fine.
