I was running test and tune in 47deg weather and had been in probably 80deg before. Steve Mick was helping me and we kept increasing jet sizes till we started going backwards in ET. I know we jumped up maybe 3 sizes. I can look it up and post it when I find it later. This was on my 318poly w/ dual quad 500 Eddy's.
