My OCD is realy kicking in on this right now...
I did some math...

TPUSA 865 kit produces a gain of..................16 hp and 5 ft-lb for a cost of $59.31 per hp or $189.80 per ft-lb (price $949.00)
TPUSA kit w/ Ignitor produces a gain of..........21 hp and 8 ft-lb for a cost of $56.86 per hp or $149.25 per ft-lb (price $1194.00)
A basic 904 kit only produces a gain of about..16 hp and 18 ft-lb for a cost of $74.69 per hp or $66.39 per ft-lb (price $1195.00)

Now...some will balk at the price for the 904 kit. Im taking the price of the TPUSA kit cause its a one stop shop AND its a 11.5:1 kit vs the 10:1 kit, jugs are done and ready to go and using the low end of the claimed results from the BP web site.
I think this is safe cause after looking over the Dyno charts NO ONES 904 mods got to those #s without more work and more $$. So...all in all I think Im giving the 904 kit more credit than its due.

904 owners...Im not ****** on your kits. I know ultimately the 904 kit will allow for greater gains overall and the initial Tq gain is significant. Thats the one thing thats still keeping me hung up on the 904 kit.
