I know that the P28 ecu makes the engine run rigch and the timing and such is off somewhat, my question is how much of a difference is there between the P28 and the P08? I mean is it a noticable difference in power or torque, or is it just 1 or 2hp?

 

My timing isn't off with my p28...

 

Timing is fine, it does run a little rich, but not necessarily enough to matter. I still average 32MPG & I don't baby it at all, others haved been getting 36-38MPG w/ a P28....HTH

 

d15b run fine off of p28 someone lied to u.

 

Mines runnin beautifly on a bone stock p28
