Mike,Dodge Nitro 2.8 CRD

Thanks very much got it fitted easily once you had shown me where to plug it. Just done a short school run and WOW was never going to be a fast car due to its power to weight ratio it was woefully underpowered.. It is a big american lump of iron after all. However have wacked the tunit up to 9 and what a difference, it now drives just so much better, I no longer have to floor the throttle to get a response from the automatic box/engine.

609.9 81.90 7.45 13.43


The first reading was with the Tunit setting at 6 (as you had set it after the Dyno) and also included the climb through the hills to Canungra and then over Cunninghams Gap to Warwick with our
