I read the safe mod info but then you go to Wbody and they tell you you can run a 3.4 with a downpipe only and the questions start.I planned on having someone flash the PCM you say zzp is 125 what about the rest?I figured a 160 stat was better i live in michigan i wont drive the car in the winterI know the PCM has to be tuned for either thermostat.Yeah the headers are a good deal but like i said i doubt i could get 3 inch under the car i figured a true 2.5 from the manifolds out would flow pretty decent for the mild mods i am doing.I will run atleast 93 octane.We have a 3500.00 Snap On Solus scanner so i will be able to check the KR.
