Shorty for special applications:

Please note we are offering an introductory price on these injectors which is competitive with other vendors pricing for non flow-matched sets.

NOTE: These injectors as well as the Siemens 57# 3172 are compatible with the LS1 PCM. Delphi/MSD 50's (17113738) have problems working with the LS1 PCM making them hard to tune.

Please see our sig below for other injector / product offerings.

 

How well do these injectors idle? Also, how much power are they capable of supporting on a blown engine?

 

Customers love them for idle as they are stable down to 1ms.
Buick owners have them idling at 0.7ms.

 

Can you say what the problem is with the 17113738 working with LS1 PCMs is?

 

The factory injector tables are considerably different than what the 17113738 requires. There is also what appear to be a compatibility issue with the LS1 PCM injector driver circuit and the coil on the 17113738 injector.

Some people have managed to get them to work well but these people generally posses advanced tuning skills.

 

siemens don't offer offset data?.. I just got a set from you yesterday. I must say i doubt the stock offsets will be close.. tuning around them is lame.
