I installed my Mach plug over the weekend. So far I am pleased. My boost went up and the truck seams to pull a little harder. I have a race on Sunday and will update with a new time (if its faster).

I hope that it will drop a tenth.

 

looking forward to your results

 

New time

11.33 @ 118mph today at the track. Best run prior to that was 11.52. All i changed was the plug. Not bad ten bucks per tenth, I wish it was always that simple.

 

can anyone tell me where to get a mack rack plug thanks alot

 

Did you look under the hood of a Mack?

Sorry.

 

Sweet Times

 

I would think if piers did your pump you shouldnt have to worry about it

 

its for a street truck i jsut purchased so just answer the dang question, quit being a moron.

 

Good deal, my next mods will be some new era 370's and a rack plug, so It sounds like I should get a good gain out of both of them. Thanks for giving real world numbers. Can you tell much difference in EGT's, and what was the boost difference? Thanks

Eric
