Another 79 series in for our clutch & remap package. Driving away with a staggering 92% more torque, and complete reliability. You know what to do!

If you think remapping is all about running cars on dyno's, then think again.
Here's a snapshot into the behind the scenes work that goes into 'remapping' some of the vehicles we see.
This is the ECU from a 2008 Isuzu truck sent to us from a customer, and well, if it looks technical - that's because it is!
Do not try this at home folks!

We've had some seriously busy weeks of late, and it's not showing any signs of slowing down!
Here are just 2 of our remaps from last week, a PX2 Ranger Wildtrak and a new Z71 Colorado.
Both picking up some great gains for towing!

What's this then??
One of our customers brought his new Ford Ranger Raptor in for us to have a sticky beek at and naturally one thing led to another annnnd we decided to run it up on the dyno and check out some figures!
These guys are a 2.0ltr twin turbo now driven by a 10spd auto.
Very cool!
Whilst the Raptor is not currently remap-able, we are certainly working on it! πŸ˜‰πŸ˜‰

Customer Testimonial's


"Today I had my PXMk2 Ranger in getting Fulcrum sway bars fitted front and back to reduce body roll when my slide on camper is fitted. Very happy with the result... And.... whilst it was in their shop - well why wouldn't you get them to put it up on the dyno and get it remapped..and wow what an improvement... very happy with it and recommend you give them a call and discuss what they can do for you on your vehicle. Thank you team GPC"


"I had my D40 Navara in for a 3 inch exhaust, and remap. I am thrilled with the results!. Improved fuel economy and the sluggish takeoff resolved as well as better performance throughout the rev range. Highly recommended!"


"I had my Isuzu NPS300 re-mapped late last year. Since then I've had some fuel and software issues, none of which were their fault, and GPD have sorted it all out. Very happy with the performance of my truck and very happy with the 'Performance' of Paul and his team!"
