I used MSD TWICE and the chips, they supplied TWICE, did not work TWICE.
I went to get the problem sorted at EA, with 100% success, now it runs perfect.
On a lighter note MSD did give me a full refund without hesitation, but a full mapping sessions was mentioned, even though it didn't need it at this level(stage three).
I can only say when I went, that PAUL, was confident the MSD chip was NOT to blame, until after exhausting all other avenues this was changed, the MASSIVE hole in the power band dissapeared before my eyes, despite all being set up according to the sheet supplied by MSD, I now run a EA chip, but going Emerlad ECU anyway as w/m is a load of crap compared with newer stuff, and on a cost/function basis it certainly is.
