Just put the new pipe on and had her tuned last week
WOW my gas on a full tank IN THE CITY in the heat, and getting very pedal heavy on 87 octane

Ugh, 87 octane will do more harm then good, go premium and dont look bad.

You DON'T need premium unless you advanced the timing or you're getting detonation.

A GT is designed to run on 87.

Wow that's alot. I get only 200 or less out of my full tank. I use 91 oct gas with some mods on it

Almost 300 miles taching between 2500-3000 RPM freeway through the hills and mountains with 4.10's, POS Predator tune. I was pretty suprised.

how much is it up there here in L.A its around 2.89 for 91

Bluffing024 · Sep 8, 2007

160-175 a tank FTL!

whyask · Sep 8, 2007

it just dropd from 320 to 291.. not bad but the military dosnt pay S$$T and most of money goes to mods and my home... so 250 miles out of a full tank in the city is WAAAYYYY better than what I was getting before (150-170)

Stang|ess · Sep 8, 2007

Like San-man said, N/A GTs are DESIGNED for 87 octane, and might actually run worse with premium. Now if your blown or advance the timing, that's a different story.

I get 300-315 per tank and I'm blown at 11PSI....

I thought the newer GT's (99+) require a higher grade than 87? I know the slow 96-98's use 87. My friends stock 01 GT runs on 91 octane.

whyask · Sep 10, 2007

yeh we had the tune at 91 (its the highest you can find in cali with out driving 4 hours to get higher) and my gas was draining quickly I was getting around 150-170 city with below 2000rpm shifts, so we re-did the tune for 87 and my gas jump to around 250 with shifting at 3k and spirited driving....weird but hell my engine is running great and my gas is better so im NOT complaining

2002GreyGT · Sep 10, 2007

Tuned for 93, running 93 and getting 250 a tank around town and 300 or so on longer highway drives keeping her around 75mph.

Mind me asking how you accomplish this? Downhill for 50 miles in Neutral with a tailwind? Secret reserve tank somewhere? You have to be running the tank to damn near last drop before filling up!
