What does raising the redline have to do with anything ?pio!pio! said:you'll actually lose power w/ the springs if you dont raise the redline since they are harder to compress. So wait on those until JWT comes out w/ a reflash..or you run a standalone ECU. Also it's somewhat poinltess w/o new pistons and rods to lower the rod/stroke ratio and lower piston speeds somewhat
Yeah but actually, with a FULL bolt-ons mods I/H/E and CAMS you would see a power increase over 5000RPM tooBodeB15 said:What does raising the redline have to do with anything ?
The QR25DE makes plenty of power around 5000-6000 rpm's .
