taking my 98 z28 m6 too the dyno tomorrow. Pretty well stock, aside from slp lid, gmmg catback and a tick performance clutch with koni shocks with eibach springs all the way around . Anyways I'm taking it tomorrow for a 91 octane tune and a ms-109 plus Octanium tune which equals out to around 108 octane. What should I expect to see? My nitrous outlet plate kit isn't in yet and won't be installed until Friday, which I have a seperate tuner working on , after I get back from the dyno . What do you guys think the difference will be between the race fuel and pump gas on a mainly stock vehicle? When I do get too nitrous, will I see more than the rated hp too the wheels while running the 108? I'm really hoping to upgrade my pump and be around 500 on a 200 shot . I use a fast dual wideband setup off both banks to monitor both sides of the engine. Let me know what you guys think and what pump would give me room to grow? Also have a set of s.d 60 lb injectors that I haven't installs yet

On 91 pump with just a lid and gmmg catback, it made 321 rwhp . Now all we changed is vp's Octanium booster, into 5 gallons of pump too see if it truly does make a difference . May do 3 more runs and some tuning with ms-109 and Octanium for 108 octane . Right now according to the Octanium m bottle we should be sitting around 100-103. I'm happy with 320 without spray on pump gas though .

Unless its pulling timing from knock retard, then increasing octane with no other changes should actually result in power loss.

The first run it was pulling timing from 5600 up, 2nd run it was still pulling a half degree. Added Octanium to the pump fuel and it had no knock retard and made the same power it did on the 2nd pull. The biggest difference I noticed in the car was mid range power after the tune. It just feels snappier and pulles harder from 2500-5500 than it did. It definitely has more up top but like I said , the gains I felt with a dyno tune were definitely in the middle of the rpm range. Tomorrow I'm hitting it with a 150 shot from a nitrous outlet plate kit, with a lnc-2000 to pull timing . I'm gonna order their "dedicated" fuel system , and the lingenfelter progressive controller and step into the 200-250 realm with the ms-109. If the motor lets loose I don't care, but I wanna try to get close to 600 at the wheels on spray, and ramp it by gear. Something along the lines of 50-75 in 1st , 125-150 in 2nd ,and 250 in 3rd

There really wasn't much point to test out the race fuel on a stock car, I may have seen 330 if that on the ms-109 and Octanium and more aggressive timing but For me to burn out 100 dollars worth of fuel plus another 100 dollar bill just to see where we could take the car on aggressive timing and race gas is pointless
