Finally got my truck back. Tunes installed (performance, 2 towing options and extreme). I must say I'm impressed I would have never imagened an '07 with DRW would set you back in your seat like that. Fuel mileage Unknown as I haven't run a tank through it yet. Is there anything I should pay close attention to.
Gauges are a good first step, but even without them,
you WILL need a better flowing exhaust system installed asap !!!!
egt's could be an issue with a tuner.....
IMHO, a quick and ez fix is the Walker BTM muffler.... lowered egt's about 200 degrees and lifetime warranty - all for $60 or so....
A turbo back system will flow the best @ a higher price point and install effort, but I've not found that I didn't need it on my 05 even though I liked it on the 03....
