Pig rich on dyno with poor numbers

The 6.1 with O2 tracking is a good option too.

It's the one I recommend. Erics chips are user friendly, easy to adjust and his instructions are second to none. Grumpy's gone into the 9's with Erics 5.7 on the default settings and I run in the 6's all day in the 1/8th on stock junk bracket racing my car with Erics 5.7 chip without even trying. Eric makes it easy.
 
Consider installing a wide band on the car. Sure, people have tuned 9 second cars with the stock o2, but why chance it at 26psi. Cheap insurance
 
It is very important to have a wide band because of it's accuracy. The narrow band becomes less accurate as it heats up'
 
It's amazing what this old antiquated POS computer can do. Bob and Eric have shown us.
