I'm currently running 10-11psi on a Vortech S-Trim LT1 (info in sig), and still on an FMU. The PCM is stock, she needs a tune BAD. I'm pretty sure I'm going to go with PCMforless.com, I e-mailed Bryan and he told me he'd program it for 42 pounders. Here's my questions-

1. Is any brand better than the other? What would you guys suggest?

2. Am I making the right choice going to PCMforless.com? Funds are limited, plans were for a dyno-tune but I can't afford it right now...


Thanks fellas

 

i was always told you want to dyno tune a supercharged car to be sure on the top end ,but im more than sure bryan can put a safe of enough tune to help until you can get it dyno tuned you just might lose a little up top as far as injectors go delphi or semenis deca(i cant spell worth a s***)

 

If you are going with 42lb injectors then I would recommend Bosch (samething as SVO). I do not think that Siemans or Delphi makes 42 lb injectors. Also if you go with 42 lb injectors then you have no need to the FMU.

 

i personally prefer the lucas 42s over the svo units. i dont like tuning the svo 42s, they are a pain in the ***. the lucas 42s pulse down a lot better.

 

Bryan said he would program the PCM for SVO 42 lbers, so the Bosch is the same as SVO? I'd be able to use the Bosch?

 

since they are the same flow rate they will interchange. when my mustang was making 500rwhp, the svo 42s were a little lean, and i got tired of the ****ty driveability. so i put lucas 42s in w/ no changes, we air/fueled the car again and it was getting more fuel w/ the lucas 42s at the same pressure and had better driveability. the thing about the lucas injectors is you dont want to run more then about 65 psi fuel pressure because they are a disc style injector. but my whole view on that is, if i have to run that much fp, its time for a larger injector.

 

Bosch makes SVO injectors.

 

its too early, i thought he said lucas. duh.

 

Thanks a lot fellas
