that's what we all like to hear if you dont hav ea whole lot of money for gauges i think the gauges are called glowshift's they;re a decent gauge for their price... isspro are top of the line and very popular. if anything go to the price quote page and see what you get offer wise from the sponsors; they treat us right

and 16-18 psi is a right around stock number; so no issues there at all... i'd like to have an accurate boost number to tell you what i'm running but my cheap gauge stops at 20; and i'm wrappin the peg around... so probably higher 20;s low 30's...

i think the H1C's upper limit is 35 psi before bad things happen... like i said idk where i sit for boost numbers... but fuel upgrade wise i'm still lacking a pin and 366 spring so i can still drive the turbo harder but idk if i really want to

i agree how should i go about the fuel pin is it better off 2 grind it down or jus buy an old smokey? im gonna order a 366 spring soon but i wanna get my guages first. if i do ne upgrades 2 the fuel pump am i going 2 have a problem getting thru inspection? or jus nip it in the bud & go to a private inspection place? it jus bugs me that @ wot i cant realy go over 75 mph w/o my engine screameing @ me 2 back off

hmmm inspections... i'd just rotate your stock fuel pin so the deepest setting on the cone is facing forward and bottom out your full fuel screw against the facotry safety collar on the stud... it'll give ya some more power w/o smoking an ungodly ammount; just when it comes to inspection time crank the star wheel way up and back the smoke screw out... this'll cut wayyy back on lwo end fueling and even effect low boost fueling... so if there are any kind of emissions test it should pass no problem... if anything they may just "grandfather" it in b/c of the year

i allready know that theres no emissions testing on my truck cuz of the year so should i jus throw a side exit exhaust on & juice it up a lil & wat happens? i mean worse comes to worse i can jus back off the smoke screw & try again the only thing i can think of that they could fail me exhaust wise is viseable smoke. see jersey is weird bout theyre rules u can have this if u meet this requirement but u cant have this without this! its rediculouse u should see the lift kit rules here theyre ridiculose!!!

If it was me I would go with the M&H pin. You can pick the profile that will work best for you truck. They are a sponcor on here too!

M&H Inc. - Diesel Bombers

I would order teh 3200 (366) spring ASAP. It wont hurt anything, EGT's will stay pretty much the same. Only time EGT's get crazy is when you start playing with teh full power screw.

depends on your liking; richieO just won the free fuel pin giveaway sponsored by M&H. he opted for the M2 and he seems really happy with it. its supposed to be a versatile pin for play and you can still tow with it. as the pin numbers go up the ramp gets steeper and deeper. the M5 is their hottest pin and it follows around the same profile the denney T stage 2, old smokey, and bully dog pin. if you have any questions i'd get ahold of M&H; who to know a product better than the people that make it personally i like the looks of the M3 progressive ramp and looks to be abit shallower than the M4 and M5
