Outer Limits 4x4 Board

i wanna get my hilux dyno tuned ( 2003 sr5 1kz-te 3.0TD) .

i put an intercooler on it but only tweaked the boost a bit but not the fuel cos you need the chip to do so .

but can they do anything performance wise like tuning and stuff without the dp chip ?or is a dynotune a waist of time without it?

go to chapmans dyno tuning in cooroy they tune most the comp trucks they tunes my mates 79 series cruiser and holy SH*T does it fly u will notice the difference
