Just going to give you a lil info on the car. 98 Formula 88k has pace setter LTs, off road y pipe to a 3 1/2 inch Borla str8 through muffler that ends behind the pass. seat. Has a that big 90mm lid,bello, stock Tbody with a c5 ZO mas. Has a LS1 intake egr delete. It has a 3500 tci nitrous stall on manual valve body built 4L60E. Stock rear end 342 gear. Car was a 6speed car.

I got the car tuned at speed inc after i fixed the exhaust and change the intake set up. The car without a tune put down 281 with a 11.1 a/f ratio after the tune 293 with a 12.5 a/f ratio.

Anyone have any idea's wtf is going on here? The car runs strong.

Well they said start with the spark plugs, coils, then compression test. My friend also said maybe the fly wheel can be messed up. This use to be a m6 car so who knows maybe they fab'd the 6speed fly wheel. A lot of stuff on the car was done pretty ghetto/cheap but not by me. At 80mph car feels like its going to fall apart, massive shaking/vibrating. Like every Fbody with a stock rear end mine makes noise b. But after the dyno I can see a fly wheel that is doing this doing this.

If it was something with the motor i don't think it would have ran as well as it did. I wish the track was open so I can see what it does know. Hell if it did like a 12.3/2 I would be amazed.

BTW tech is fine other than being off very little, which is normal for these cars.
