I recently made contact with Will from Overkill to inquire about a Tuned PCM for my 02 GTP and we exchanged a few e mails in which he answered some questions that I had relative to my Mods, I then went on his website and made a purchase, 5 business days later I had my new custom tuned PCM in my hands and I am in Vancouver!
The PCM he sent me came with very explicit instructions regarding install and more often than not to expect to do a Crank Shaft Position Relearn Procedure.
I followed his instructions together with his recommended 180* thermostat install and alas I was up and running, no strange warning lights or check engine lights and no need for a CSPRLP!
My car is running awesome and instantly felt the difference in the way the Tranny shifts and the power is way more constant and readily available, no more bogging down, constant smooth flowing power!
My overall experience with Will was very positive, this guy knows his stuff and really does know these cars and to anybody looking for a custom tuned PCM he is the man!
