Cobb vs UpRev

Denny McLain

Not sure if you got the point.

LT1.edit is a tuning program for LTx motor F-bodies and Corvettes that tweaks the stock ECU. In this case it was a 97 SS Camaro with extensive modifications. The stock ECU was originally tuned at Dynotech using the LT1.edit and even with engineering tuning support from Haltech, they could not improve on the stock computers ability to control the engine and produce horsepower. Bob Norwood at that time used the same dyno and popped in for a couple of sessions.

Think you'd be very hard pressed to find a better tuner.

Guessing a dozen dyno sessions at least looking for the holy grail. One night alone we started about midnight and stopped about 5:30 am going through two tanks of gas driving the hwys' around Dallas at different load levels to fine tweak the tune.

Not saying anything bad at all about Haltech except that the stock ECU on certain cars can be very hard to improve upon. Not a slam dunk by any means and I seem to recall the factory has a few engineers themselves with pretty deep pockets for R&D.
