26 Long Trips MPG
 

After 26 long trips totaling 21,249 miles the average MPG is 27.99MPG. These particular trips are all greater than 800 miles. Modifications Volant intake and exhaust. Pulstar plugs and high performance plug wires.:shade:

did you log your ave speed?
 

just curious as I tend to 'stretch' the speed limit rules on road trips

Re: 26 Long Trips MPG
 

will that void warranty and is it using premium or regular?

Re: 26 Long Trips MPG
 

Jet 1 the average speed during these trips was 51MPH. Evios I did talk with the dealership and they had no problems, I have been a GM owner for many years and have always used Goodwrench Service on my new vehicles. I have also helped two GM dealerships sell two Tahoe Hybrids by supplying data and my vehicle as a demo. Also please note that these trips were completed under ideal conditions, very little traffic, two lane roads, hilly at times in northern Ontario. Being able to slow down keeping the ECO meter dead center in the green and excelerating in EV mode slowly taking the maxmium benifit possible. This is a great vehicle just needs more advertizing. Also data is combined fall/winter time frame.:shade:

Ken,
Thats great thanks for your feedback very impressive indeed

Re: 26 Long Trips MPG
 

any pics of the volant CAI? did you use their dry vs oiled filter? with your exhaust, did it change the sound of the hybrid when it goes V4?

Re: 26 Long Trips MPG
 

Jeremy in the next day or so I will try and post a picture for you of the Volant CAI, the new dry blue Powercore Filter is what I am using. Great filter. The Volant exhaust did change the engine noise level in all areas V8 and V4 slight increase in noise looks good though. Interesting and I had forgot to post this but the high performance ignition wires are a lot 2Lbs lighter than the old style standard wires with metal connectors looks like they came off a Russian MIG.:shade:

Ken that is really, really impressive. I imagine it was pretty cold in Northern Ontario during the end of February!

well...
 

i guess I won't achieve those figures as 51 is a number I briefly vist on my way to 80+:embarass:

Down here in SoCal, 51mph is something you try to keep it under when you are in your driveway...
