Well ordered the Gryphon
ordered mine last week also, suppossed to be sent tomorrow or tues. can't wait. have the hypertech pp3 now, but it's outdated. with gas being 1.43/litre, any improvement will help. that's for reg. i ordered 87 octane tow, 87 performance and 89 performance. 89 won't be run much with premium around 1.50/litre. my truck is an xl, so i don't even have a tach. that's what swayed me to the gryphon. the gauges are what i need/like.
If your right foot enjoys the new toy as much as mine does I wouldn't expect a jump in MPG right away. I know I've been driving with more throttle than usual just for the fun factor since I've put it in. I'm sure after the new wears off I will go back to conservative driving
