its pathetic really, coz its pretty hard to NOT make a 5L go better with a tune

Carbs not that bad.....well..OK.. yes they were...there wasn't a great deal of control over things and they were like pouring fuel straight into the manifold especially if you have a roots blower on top and a bored out chevy V8 under it!!!...I agree with holden202...the chips do not take into account all the variables, engine condition, etc and considering that the entire program, not just the tables as I first assumed (I assume too much!!) are on the memcal ..it seems risky to put any chip in the car when you are not absolutely confident of its author....
