i used to use a meth kit on my 89 tta with great results,23 psi and 25 degrees of timing on 93 octane.has anybody run an unported eaton at 17 psi w/alky and 20-23 degrees of timing.iat2 numbers should be down significantly and the alky increases the octane of 93 premium.i was very suprised to see so many cobra owners that say alky doesn't work.it sure worked wonders on my tta.thanks for any input.
