They have never let the ME run in the GSCA Nats because it is considered an unfair advantage. This year it was allowed to run TSM with the DFI cars.
One of Louie L's cars finished #2 running a ME. I think he should have put a Power Plate on it after seeing what Jason was running.
Both the Extender and ME are excellent chips, no doubt. The ME is aimed at giving the owner the fastest chip out there without being concerned about the emissions side of things. Because of the inidividual features which may be easily tweaked by the owner, it is easy to accomodate various engine combos.
The Extender is a very innovative chip as well. It is probably aimed at a larger audience and should pass emissions testing when set on closed loop. It has some features added that try to give it some features of the ME like lean cruise and launch assist.
I am a very strong fan of the ME and I like some of the built in features like the automatic enrichment when detonation is sensed, the ability to adjust richness as desired for spool up and launch and then select a fuel curve for the rest of the run that is different. I also like the ability with larger injectors to move the entire block of fuel curves up or down to accomodate the boost being run. When running alky and higher boosts all the time, this is not as critical as it might be when switching from 16# on 93 to 28# on 116, but, it still allows one to set the normal selected fuel curve to a lower tw number so there is plenty room always left for enrichment if detonation is occurred and the chip starts adding fuel.
It is an extremely streetable chip unless one wants to pass a strict emissions routine. Drivability is outstanding and the ability to adjust for tb size and accelerator shot makes it easier to dial it more extreme combos.
I am sure you would be happy with either chip. Two of the premier chip guys around. It really depends upon what you want, I think.
I have used ME's with 36#, 40#, 42.5#, 50#, and 75# injectors. Currently I am running 36#, 50#, and 75# injectors in my three cars with ME's. I want to find some time to try the new mafless prototype that is being tested. If Red can go to a four inch maf, I think Steve Y is on the right track in just eliminating it. If he has to run with the DFI cars, he might as well just call it DFI and be done with it.
