First off I have a pcmforless mail order tune on my car right now. Is there any way that I can change the size of the injecters on this tune myself? If so what program could I use. This is a 93 LT1 and I already have a chip burner and wideband. The reason I ask is because I emailed pcmforless about a week ago and never heard anything and I am going to the dyno next Saturday and need the injecter size changed from 24 to 32.

 

tuner cat http://www.tunercat.com/tnr_desc/do_tc.html works for 30 days for free.
and the $DA3 def file. monodax.com is a good tuner cat forum if you have problems.

I would like to know if tunercat is easier to use than LT-1 edit and which one is more just plain easy to use.

 

I have only used tunercat and tunerpro rt, lt1 edit is not used for 93's. I personally like Tunerpro RT better due to the fact I can simultaneously datalog and realtime tune (with moates autoprom) and has a data trace function to track what cell is currently being used.
