Replying to: okko1 (Aug 19, 2007 3:28 pm) Yep. The bigger the engine and the higher the rpm, the more HP will show on the dyno (and it will be modest at best). Replies to this message: paisan (Aug 19, 2007 7:56 pm)

Replying to: Mr_Shiftright (Aug 19, 2007 5:45 pm) I agree, especially on 4 cylinder cars, intake and exhaust will be modest at best.   -mike
#21 of 21 GM 4.3 HP Increase, MPG increase by tc07 Sep 27, 2007 (5:36 am)
Replying to: the_big_al (Jun 27, 2008 3:16 pm) On GM's 4.3 engine with distributor ...up to at least 2001 model as I had, Put on an MSD Ignition, HP distributor module, rotor and cap. Next add MSD ignition coil and Taylor (or a good set) of wires. Then put in AC Delco Rapid Fire or Bosch +4 sparkies. I did this and GAINED 5 MPG highway and Dyno'd 28+ HP! I then added Hypertech Power programming due to having to put on 245/50/15 tires and traction bars to get needed traction on dry pavement...not to mention wet.   In all the MSD ignition more than paid for itself in gas savings the first year I had the S-10, EXT Cab and LS Sportside bed. I just sold it after having it 7 years.
